BackgroundOrgan donation has become one of the most effective ways to save lives and improve the quality of life for patients with end-stage organ failure. No previous studies have investigated the preferences for the different consenting options for organ donation in Egypt. This study aims to assess Egyptians’ preferences regarding consenting options for posthumous organ donation, and measure their awareness and acceptance of the Egyptian law articles regulating organ donation.MethodsA cross sectional study was conducted among 2743 participants over two years. (...) Each participant was required to rank eleven consenting options from 1 to 11, and to report his awareness and acceptance of the seven articles of the Egyptian law of organ donation.Results47% of the participants expressed willingness to donate their organs after death. This percentage increased to 78% when consenting options were explained to participants. “Informed consent by donor only” was the most preferred type of consent for one third of respondents. Awareness of the law articles regulating organ donation was relatively low ranging from 56% to 23%.ConclusionCurrently, around half of the Egyptian population agree to posthumous organ donation. This percentage could be increased significantly by raising the awareness about how the process of donation could be regulated and how the patient’s right of decision could be protected. (shrink)

Background The nursing profession requires ethical and legal regulations to guide nurses’ performance. Ethical climate plays a part in shaping nurses’ ethical practice. Therefore, ethico-legal aspects and ethical climate contribute to improving nurses’ ethical practice and competencies with reducing medical errors in hospital settings. Objective This study examined the effect of ethico-legal aspects and ethical climate on managing safe patient care and medical errors among nurses. Materials and methods A cross-sectional correlational study was carried out on 548 nurses. Data were (...) collected through self-administered questionnaires about nurses’ knowledge in both ethical and legal aspects, ethical practice, competencies, ethical climate and experience with medical error. Results The main sources of nurses’ knowledge of ethical and legal aspects were undergraduate lectures, job experience and colleagues. Nurses’ knowledge in both ethical and legal aspects, nurses’ ethical practice and competencies were insufficient. Nurses fairly perceived their ethical climate. Also, nurses experienced medical errors about 22.6% in their units. Nurses’ knowledge of ethical and legal aspects, as well as the ethical climate were positive predictors of inadequate nurses’ ethical practice and competencies. Additionally, nurses’ knowledge in both ethical and legal aspects, ethical climate and practice had a negative influence on the occurrence of medical errors. Conclusion Enhancing nurses’ knowledge in both ethical and legal aspects as well as ethical climate could significantly influence improving nurses’ ethical practice, competencies and reducing medical errors in the study units. Therefore, planning for enhancing the nurses’ ethico-legal learning and ethical climate seems to be mandatory. (shrink)

Background Workplace silence behavior is a social collective phenomenon. It refers to nurses choosing to withhold their ideas, opinions and concerns about critical issues in their workplace. Workplace silence behavior poses a threat to organizational ethics and success. It also has adverse effects on the performance of nurses in health organizations. Underlying nursing causes of silence behaviors could be related to individual, social and organizational attributes in health care settings. Objectives The study aimed to develop a new Egyptian validation scale (...) for measuring nursing motives of workplace silence behavior and identify consequences of workplace silence behavior on nurses. Methods A cross-sectional correlational study was implemented using questionnaires on workplace silence behavior, nursing motives and nurses' consequences, collected from 332 nurses working in critical and toxicology care settings of Alexandria Main University Hospital. Results Egyptian scale was shown to be a good fit model of exploratory (36 nursing motives emerged in six dimensions with total variance of 73.3%) and confirmatory factor analysis tests (X2 = 1381.47, NNFI =0. 90, CFI = 0.91, RMSEA = 0.057). It also had high reliability tests with coefficient of alpha (0.85), Pearson (0.75) and Kendall coefficient of 0.72. High level of workplace silence behaviors showed a negative association with organizational dis-identification, fair citizenship behavior, and fair nurses' performance and declined reporting of patient adverse events. It also appeared to be in a positive association with higher levels of cynicism. Conclusion The Egyptian scale was proved to be reliable and valid for measuring the underlying nursing causes of silence behaviors in the hospital workplace. Measuring nursing motives of workplace silence behaviors will help nurse managers to reduce negative outcomes of workplace silence behaviors and improve organizational outcomes. (shrink)

The ternary xV2O5–(40 − x)Li2O–60B2O3 glass system, where x = 1, 2, 3, 4 and 6 mol%, was prepared by normal quenching. Ultrasonic velocities and attenuation were measured at room temperature using a pulse-echo technique. Various parameters, such as elastic moduli, micro-hardness, Poisson's ratio and Debye temperature, were determined from the measured densities and velocities. The composition dependence of these parameters, in addition to the glass-transition temperature, suggested that vanadium ions were incorporated into these glasses as a network modifier, resulting (...) in the reconversion of BO4 tetrahedra to BO3 triangles by the breaking of B–O–B linkages and the formation of nonbridging oxygens (NBOs). The outcome was a reduction in network connectivity and rigidity with increasing V2O5 content. The results are explained quantitatively in terms of fractal bond connectivity, average atomic volume, network dimensionality, packing density, number of network bonds per unit volume, cross-link density and atomic ring size. The Makishima and Mackenzie model appears to be valid for the studied glasses when the fate of BO4 tetrahedra and creation of NBOs are taken into account. (shrink)

This article argues that the reception of the work of Cheikh Anta Diop by French historians and Egyptologists is a case of epistemic injustice as this concept has been defined by the British philosopher Miranda Fricker. I first explain the concept of epistemic injustice and then show, using Popper’s demarcation criterion, that it is impossible to objectively reject Diop’s work as lacking in scientificity. I thus analyze the heterogeneity of Diop’s work reception depending on the positionality of the actors in (...) the French scientific field and conclude that this reception is only understandable if we analyze it as an illustration of the phenomenon of epistemic injustice.

Along with Sahîh-i Bukhari, many commentaries and memoirs have been made on Sahîh-i Muslim, which is accepted as the most reliable source of hadith and consists of sound narrations. Among the commentaries written today, the comprehensive commentary, which is a product of labor that cannot be ignored and stands out whit some features, is Ethiopian scholar Mohammed b. The commentary of Ali al-İtyubî’s Sahîh-i Muslim commentary on al-Bahru’l-muhît and his holy book is Kurratü ayni’l-muhtâc. This article aims to briefly introduce (...) İtyûbî with his educational life and Works, the method he followed in his annotations, the sources he used, his reports that do not require many works, his criticisms and evaluations, his perspective, his world of thought, and to reveal and evaluate his different approaches and ideas on certain subjects. Reaching 47 volumes together with the Commentary on the Muqaddima, the work has the feature of being the widest commentary of Sahîh-I Muslim. By transmitting the information in the previous works in a compact and collective manner, he did not leave the need to apply to them, and he made the hadiths easier to understand whit the memzuc method that explains word by word. The extensive interpretation of hadiths, the mention of different narrations, and the fact that the judgments derived from hadiths are regarded as material are some of the issues that make commentary important. This article aims to briefly introduce İtyûbî with his educational life and works, the method he followed in his commentaries, the resources he used, his transmissions that do not reguire many works, his criticisms and evalua-tions, his perspective, his world of thought, and to reveal and evaluate his different approaches and ideas on certain subjects.

This paper investigates the objections that were raised by the philosopher ‘Abd al-La&tdotu;īf al-Baghdādī against al-&Hdotu;asan ibn al-Haytham’s geometrisation of place. In this line of enquiry, I contrast the philosophical propositions that were advanced by al-Baghdādī in his tract: Fī al-Radd ‘alā Ibn al-Haytham fī al-makān, with the geometrical demonstrations that Ibn al-Haytham presented in his groundbreaking treatise: Qawl fī al-Makān. In examining the particulars of al-Baghdādī’s fragile defence of Aristotle’s definition of topos as delineated in Book IV of the (...) Physics, which was rejected on mathematical grounds by Ibn al-Haytham, a special attention is also given to highlighting the systemic distinctions between the entities that are studied within the speculative physical doctrines of common sense and immediate experience, and the postulated ‘objects’ of scientific and mathematical research.

The quality of the narrations of 'Abdullah b. Salih al-Misrî (d. 223/838), one of al-Bukhârî's famous teachers, in al-Jâmi al-Sahîh has been a matter of debate among hadîth scholars. Abdullah b. Salih, whose narrations are narrated by Abu Dâwûd, al-Tirmidhî and Ibn Mâjah, is an important figure whom al-Bukhârî interviewed and also narrated from him in his works such as al-Adab al-mufred, al-Kirâʾa Khalfa al-imâm and al-Târîkh al-kabîr. However, whether he narrated directly from him in al-Jâmi al-Sahîh has been a (...) matter of debate among the scholars of Hadith. Ismâ'îlî (d. 371/982) and al-Hâkim (d. 405/1014) claim that al-Bukhârî did not narrate any hadîth from him in his Sahîh, while al-Zaḥebî (d. 748/1347) and al-'Aynî (d. 855/1451) argue that he did. It is possible to say that this disagreement is due to two reasons. The first is that there are differences between the copies of the Sahîh, and the second is that al-Bukhârî mentioned some of the narrators in an incomplete form. In this study, we will investigate various copies of the Sahîh and focus on whether the person whose identity is mentioned as "Abdullah b. Sâlih", "Abdullah" and "Abû Sâlih" in them is really Abdullah b. Sâlih al-Misrî. In addition, we will touch upon the evidences relied upon by the muhaddithis who express an opinion on this issue in terms of narration and dirāyah, and we will also draw attention to how the sîgas of tahammul and âdâ used in the narrations should be understood. Finally, we will try to determine whether al-Bukhârî has made any tahrīj from 'Abdullah b. Salih in his Sahīh, and if so, for what purpose, i.e., for ihtijâj or istishhâd. (shrink)

This paper presents a unique manuscript copy of a fifth/eleventh-century Maghribī commentary on al-Bāqillānī’s Kitāb al-Tamhīd. The work, entitled al-Tasdīd fī sharḥ al-Tamhīd, was written by ‘Abd al-Jalīl b. Abī Bakr al-Dībājī —also known as Ibn al-Ṣābūnī— who had studied the Kitāb al-Tamhīd with al-Bāqillānī’s disciples in Qayrawān. The present study first reviews the transmission of al-Bāqillānī’s work to the Islamic west. It then continues to present the author of the commentary, to reconstruct the work’s genesis and to describe its (...) content. The final section focuses on a sample chapter and argues that al-Dībājī follows al-Bāqillānī’s later position on a specific theory —the so-called theory ofaḥwāl— of which the Tamhīd strongly disapproved. The Tasdīd is one of the oldest texts of Maghribī Ash‘arism that has come down to us and provides valuable new insights into the school’s early history in the Islamic west. (shrink)

The type of ‘Al-isnād al-āli’ (higher chain of authority) which has great importance for the science of ḥadīths that constitutes the second best source of the Islam, expresses the value in terms of its proximity to the period of the Prophet Muhammad (peace be upon him). If ḥadīth has ‘al-isnād al-āli’ in the works of the scholars provides us with assurance on the intend of the ḥadīth. For this reason, the values of the works of those authors who have constructed (...) their works with al-isnād al-āli undoubted in the science of ḥadīth. However the work of Abu al-Jahm al-Bāhilī’s (d. 228/842) named al-Juz‘ had that kind of ḥadīth, it has not appreciated by scholars, he could not get enough attention in his period and after it. His work contains famous scholar al-Layth Ibn Sa‘d’s (d. 175/791) narrative who claimed by ḥadīth scholars that his students neglected and omitted his ḥadīths and knowledge. Al-Layth Ibn Sa‘d was known doing transmission by written copies. The similarity of al-Layth Ibn Sa‘d narrations in al-Juz‘ with al-Layth narrations, which are also found in other sources, strengthens the claims of the existence of a narrative process based on the written texts in the early periods. In this study, these transfers of Abu al-Jahm reflected on other works will be examined and tried to build narrations of his teacher al-Layth Ibn Sa‘d. country, we can say that the article will contribute to the studies of the history of religions.Summary: Ḥadīth works written in the third century of hijri are the most distinguished sources. The most fundamental works in the science of ḥadīth were written in this time. In the following period, numerous studies have been committed to paper on them. One of the eminent works is the named al-Juz’, which belongs to Abu al-Jahm al-Bāhilī (d. 228/842). The author was not a person that was taken into consideration much during his time. It is possible to that he has been criticized about his scientific proficiency (al-Jarh). Nevertheless, al-Juz’ attracts attention due to the fact that it contains the type of ‘al-Isnād al-āli’ (higher chain of authority). Al-Isnād al-āli, which means access with the least number of narration from the author to the Prophet has very major role to determining of being dependable and certainty of the ḥadīths. The work of Abu al-Jahm which contains the ‘al-Isnād al-āli’ did not attract enough attention. However, another value of the al-Juz‘ is that its been included the narration of famous muhaddith Al-Layth Ibn Sa'd (d. 175/791). He is one of the valued mujtahid imams who have played an active and important role in second century of hijri. Al-Layth's narrations have been available insufficient amount present day. At this point the al-Juz‘ of Abu al-Jahm has great important because it contains many narrations of his shaykh Al-Layth Ibn Sa'd.The Juz‘ seems to has attracted the attention of the ḥadīths scholars in the following period. Indeed, various authors had the get authorization to narrate al-Juz‘. Furthermore, it is also known that some scholar in his period utilized his narration in their own study. For in¬stance, it was declared by Ibn Ḥajar (d. 852/1449) that al-Bukhārī (d. 256/870) had a narra¬tion belonging to Abu al-Jahm in his work ‘al-Ṣaḥīḥ al-Bukhārī’ with a muʻallaq chain (Omit¬ting his name). In the following periods, we come across famous muhaddith such as Aḥmad b. Ḥanbal (d. 241/855), al-Ṭabaranī (d. 360/971), Abū Bakr al-Marwazī (d. 292/905), al-Dāraquṭnī (d.385/995) and al-Bayhaqī (d. 458/1066) who received qualify of Juz's narra¬tion. Although the narrations of Abu al-Jahm are included in the prominent works of schol¬ars, it is clearly seems that the Juz‘ had not enough value except being procure as a written text. As far as we determined there are eleven narration of Abu al-Jahm in the main ḥadīth sources. In addition, we detected that some studies which contain some ḥadīth of al-Juz’ are list them in the same layout and order. This situation indicates that al-Juz’ is owned by these people as a duplicated edition and they narrated by not only orally transmitted but also spread by writing copy. This inference strengthens the theory which conceived by Modern researcher Fuad Sezgin (1924-2018) that ḥadīth transmission had conducted not only through oral transfer but also through written copies.Even though he lived in a very active time of oral transmission of ḥadīth and the time of specific journey for learning and pursuing ḥadīth, it is seen that Abu al-Jahm formed his Juz‘ from the ḥadīths that he procured only from his six shaykhs. That was quite less amount in that period. Juz‘, has an ʿAlāʾ al-Rijāl classification (ranked according to narrators) as ex¬pected in his period method. Abu al-Jahm began his study with his shaykh Al-Layth Ibn Sa'd’s narration, then completed with Sufyān ibn ʿUyayna’s. Juz‘ includes 112 ḥadīths. Ex¬cept two muʻallaq isnāds (omitting one or more narrators), all of ḥadīth has muttaṣil isnāds (narrators in the chain connected each other without omitting). Al-Juz‘ available nowadays in a published form. It seems that some of ḥadīth datas included in the Juz‘ have content against Islamic juris-prudential judgements. For example, the Prophet’s sayings ‘One or two swallow of breast milk does not make haram’ and ‘Nobody can fast or pilgrimage for the benefit of someone else’; allowing to Subay‘a al-Aslamī to marry without waiting her ‘iddah (waiting period of a woman after the death of her husband or divorce); when she gave birth, ʿUthmān b. ʿAffān’s permission to al-Rubay‘a bint Mu‘avvidh not to wait her ‘iddah; when ʿAbd Allāh b. ʿUmar has nasal bleeding he leaves the prayer, goes to wash, then back and continue where he leave off, without taking ablution; and describing marriage with polytheist women as for¬bidden (ḥarām). Of course, all this information must be examined within the framework of Islamic jurisprudence. However, Abu al-Jahm stands alone (tafarrūd) in such issues, it can be seen as the reasons to be recognized as a censured person (majrūḥ).Al-Juz‘ included 66 isnāds of Al-Layth Ibn Sa'd’s narration. Therefore it leaves behind all the works that compile the narration of Ibn Sa'd. That is why, we hypothesize that Juz‘ is a form of Al-Layth’s study that has survived to the present days. As a matter of fact, the muhaddiths who included the narrations of Al-Layth in their works, especially Ibn ḳuṭlūbughā could not ignore the Juz‘ of Abu al-Jahm; on the contrary, they took it as reference. In this case, it should be said that Abu al-Jahm al-Bāhilī is a loyal follower of Al-Layth and the word at¬tributed to Imām Shāfi‘ī and characterizing Al-Layth’s followers with disloyalty is invalid.

Hadiths that have been discussed in this paper consist of narrations regarding divine attributes and having some problematic meanings between supporters of Bişr al-Marīsī and ʿUthmān al-Dārimī. These narrations were mostly accepted denounced (munkar) by Bişr al-Marīsī and his sopporters due to having an anthropormophist and corporealist content about God. They rejected divine attributes according to their understanding of God based on incomparability (tanzīh) which provided by Mutazilite approach towards divine attributes even though they conveyed some features of Ahl al-Ra’y. (...) They found contradicted of attributing human features to God based on their tanzīh understanding, therefore, they interpreted such this kind of narra-tions in terms of their approach or rejected at all. At the other hand, a hard Hadith scholar Uth-man al-Darimi believed that one should accept divine attributes as they are in the Qur’an and Sunna. According to his belief, he considered the explicit meanings of the narrations without interpretation of divine attributes, and based on his perpective he denied Bişr al-Marīsī and his supporters’ interpretations claiming they would cause divesting God of all attributes (ta‘tīl). He argues that these narrations should be taken into considerations based on their explicit mea-nings. The discussions on these hadiths are important due to showing different approaches of scholars from the schools of Ahl al-Ra’y and the ones from Ahl al-Hadith towards the hadith du-ring the period when the main Hadith works were collected. Discussions on the narrations stu-died in this paper reveal two schools’ understandings of divine issues, their approaches to divi-ne attributes, as well inform us their perspectives of hadith in general.Summary: The present paper examines the debates between ʿUthmān al-Dārimī (d. 280/894) and the supporters of Bishr al-Marīsī (d. 218/833) on the divine attributes mentioned in some hadiths in the period when the main hadith books were composed (i.e., III/IXth century). These debates that took place between the scholars of Ahl al-Hadith and Ahl al-Ra’y concern the un-derstanding and interpretation of the hadiths in a certain way.It could be stated that the debates focus on how the hadiths should be understood, or whether it is the explicit meaning of the words or the possible methaphorical meanings beyond them that should be considered.It is worth briefly introducing the parties who discussed the hadiths studied here. The aforementioned discussions about some hadith narrations are between the supporters of Bishr al-Marīsī and ʿUthmān al-Dārimī, one of the important figures of the Ahl al-Hadith who wrote a separate work on these hadiths. This work was written as a rejection of the views of Bishr al-Marīsī and his two students on the attributes of God and some issues regarding hadith.Bishr al-Marīsī was regarded as an important scholar of Kalam who received fiqh education from Abū Yūsuf (d. 182/798). He is a scholar of Ahl al-Ra’y who made scientific dis-cussions with many scholars including Imam al-Shafiʿī (d. 204/820). He was on the council of the Caliph Al-Mamūn (d. 218/833) and had a significant role in the adoption of the idea of the createdness of the Qurʾān (khalq al-Qurʾān).Uthmān al-Dārimī,on the other hand, was a scholar of Ahl al-Hadith who learned ha-dith from the authorities of his era such as Yaḥyā b. Maʿīn (d. 233/847), ʿAlī b. al-Madīnī (d. 234/848), Isḥāq b. Rāhawayh (d. 237/851), and Aḥmad b. Ḥanbal (d. 241/855). Having visited all the important cities for the training of hadith, he learned the hadiths and conveyed them.With the understanding of proving the divine attributes and the opposition of the misin-terpretation of the narratives related to them, the groups advocating the appropriation of these lines in accordance with the understanding of incomparability (tanzīh) have complied the works since the first period. According to ʿUthmān al-Dārimī, the rejection of the divine attributes by Mu'tazila was influential in the emergence of the criticism literature of the Ahl al-Hadith and many authors wrote works in this direction.Regarding a narration by Abū Hurayra, an opponent reports that this narration gives the impression that God has the eyes and ears as we know. ʿUthmān al-Dārimī reports that this hadith proves sight and hearing not the eyes and ear organs. He indicates that God has no like by no means. Therefore, it is slanderous to refer the claim that Allah is made of organs to the Ahl al-Hadith. Abū Dāwūd states that with this hadith the attributes of sight and hearing for God are proved and Jahmiyya’s denial of the divine attributes are rejected.The opponent also considered Abū Hurayra's narration referring to the Prophet: "Faith is from Yemen, wisdom is from Yemen! I feel the breath of your Lord from Yemen!" as denounced (munkar). Because, according to Bishr al-Marīsī and his companions, breath can only come from those with an abdominal cavity, and Allah is free from it. According to ʿUthmān al-Dārimī, the opponent misunderstood. What is meant here is the wind that blows from Yemen and comforts people. In the context of this narration, we see that supporters of Bishr al-Marīsī evaluate the narrative literally, while ʿUthmān al-Dārimī interpret the narrative.Regarding the narration, "You can not approach Allah with something more virtuous than what comes out of it (the Qur'ān)" Ibn al-Saljī reports that Mushabbiha understands this as one with an abdominal cavity and from whom speech comes out. This understanding is in-valid since God is "samad" in the sense that He has no void. With this hadith, it is meant that the Qur'ān comes out of Allah’s presence rather than Allah. According to ʿUthmān al-Dārimī, the real aim of Ibn al-Saljī is to deny God's attribute of speech. There is no doubt that the Qur'ān comes from Him, and those who do not accept it merely deny His attribute of speech.Attributed to Ibn Abbas; The meaning of "yamīn Allah" (the right hand of Allah) in narration "Black Stone (al-ḥajar al-aswad) is the right hand of Allah on earth, handshakes with the people" is not the right hand that we know according to Ibn al-Saljī, it is blessing and grace of Allah. According to ʿUthmān al-Dārimī, who acknowledges that Black Stone is not meant to be a hand, the purpose of Ibn al-Saljī is to deny the two hands mentioned in the verses and ha-diths about Allah with invalid interpretations.ʿUthmān al-Dārimī, who criticized that Ibn al-Saljī quoted from another narration which Ibn Abbās heard from the Prophet, says that such poor narrations should not be spread. In addition, he points out that Ibn al-Saljī's interpretation is ugly and he criticizes it. Because Allah who is mentioned in the narrative is depicted as a young man with curly hair in a green suit. Such a narration is also an untrustworthy narration as it contradicts the authentic narrations of the Prophet. ʿUthmān al-Dārimī, who made this assessment of the narration, rejects the com-ments that the opponent made about the narration. According to the opponent, the phrase "I have come to Allah" means "to come into the presence of Allah in the Garden of Eden." Accor-ding to ʿUthmān al-Dārimī’s understanding, such complicated hadiths should not be only narra-ted.About the narration that are based on the Prophet and he does not know the answer to what he has come to know of himself, then he feels the coolness of his fingers as he puts his hand on his back and learns everything, the opponent evaluates the following: He was not Allah who came to the Prophet, but a well-behaved angel who was being directed by Allah and he was the angel who put his hand. ʿUthmān al-Dārimī rejects this interpretation of that oppo-nent. This comment is also contrary to other authentic hadiths. After he refused to the com-ment of the opponent about relevant narration, ʿUthmān al-Dārimī stated that he could not trust this comment on the basis of the authentic narrations he mentioned.Salaf scholars have preferred to be silent in this regard, as it is seen among the most difficult subjects to talk about divine attributes. However, subsequent generations have held dif-ferent paths in this regard. The basic approaches to understanding the divine attributes can be summarized in three main titles: tafwīd, tashbīh, and ta’wīl. Tafwīd is the path adopted by the early salaf scholars and means to leaving the knowledge about Allah’s entity and attributes to His knowledge. Tashbīh means to compare Allah to the created or the created to Allah. Ta'wīl is to interpret the Qur'ānic verses and hadiths that give the impression that Allah is like the crea-tures with semantics and rational deduction. The ones who deny the adjectives are called as Muʿattila and those who prove their attributes are called as Sifatiyya. According to Ahl al-Ra’y, it is necessary to appropriately make interpretation (ta'wīl) of the attributes giving the impression of anthropomorphism in terms of the dictionary. In the divine attributes, Muʿtazila advoca-ted the incomparability (tanzīh), whereas Ashʿariyya and Māturīdiyya adopted interpretation in accordance with incomparability. Mushabbiha and the Wahhābī-Salafī understanding has also taken the expressions regarding divine attributes with their explicit meanings.The debate between the scholars who lived in the ages II/VIII and III/IX, when the most important works are composed in the science of hadith, is important in that it is the first turn. In addition to this, the debate also contains important information on the approach to the Qur'ānic verses and hadiths, in that it shows two basic approaches, one of which represents the school of Ahl al-Ra’y, and the other represents the school of Ahl al-Hadith.ʿUthmān al-Dārimī generally advocates adhering to the explicit meaning of the narra-tion, while Bishr al-Marīsī and his companions criticize the narration labeling it as denied (mun-kar) or making an interpretation. On rare occasions, the places where ʿUthmān al-Dārimī re-jects the narration and makes interpretation, or where Bishr al-Marīsī and his companions de-fend the narrative can be seen.Interpretations made by Bishr al-Marīsī on the problematic narratives have influenced on the next scholars. Alongside Muʿtazilite scholars such as al-Jubbāʾī (d. 303/916), Qāḍī ʿAbd al-Jabbār (d. 415/1024) and Abū l-Ḥusayn al-Baṣrī (d. 436/1044), his interpretations have been quoted by Sunni scholars such as al-Ghazālī (d. 505/1111), Ibn ʿAqīl (d. 513/1119) and Fakhr al-Dīn al-Rāzī (d. 606/1210).The fact that the truth can be put forward in the science of hadith, which is based on the narration, does not favor one of the "narration" and "ra’y", it should be kept in mind that both of these depend on the proper and balanced use of both. To reveal the truth, the narration is in need of the opinion and the opinion (ra’y) is in need of the narration. Narration and opinion sho-uld be seen as complementary elements, not each other's opponents. (shrink)

al-Zarkashī, an ethnic Turk, is an important hadith, fiqh and commentary scholar who lived during the Mamlūks period. He was taught by some of the leading scholars of his era, such as Alā al-Dīn Mughultay (d. 762/1360), Imād al-Dīn Ibn Kashīr (d. 774/1372) ve Jamal al-Dīn al-Asnawī (d. 772/1370), and he grew up under their mentorship. Nevertheless, his only well-known student is Birmāvī (d. 831/1428). Almost half of his works have been related to fiqh and methodology of fiqh, and he (...) has also written some important works in the field of hadith. Among these, especially al-Tadhkira, al-Nukat alā Ibn al-Salāh, al-Nukat alā al-Umda fī al-Ahkām ve al-Icāba are worthy of mention. The work named al-Tadhkira, which we built our work upon, is the first known work to have been preserved in the field. Due to his being a first in his field, he was vastly studied as to how he evaluated the narrations and what kind of procedure he followed. In this work of his, not only the criticism but also the application of the text criticism adds to the importance of the work. Then, on the basis of this work, scholars such as al-Sakhāwī and al-Aclūnī made complementary works on the same subject. Summary: It is inevitable for a person to be shaped by the society he lives in. During the time when al-Zarkashī lived, Egypt was under the rule of the Mamlūks. The history of Mamlūks is examined under two periods: 1. Bahrī or Turkish Mamlūks (745 / 1344 - 794-1391) 2. Burjī or Circassian Mamlūks (784 / 1382 - 923 / 1517) period. Our author lives in both periods. About forty years of his life was in the period of Bahrī and the rest was in the period of Burjī. In both periods, the state did not have a full political authority in the country, but this was not the case in education and training. In fact, on the contrary to the political situation, scientific activities have accelerated by the arrival of many scholars to the land of Mamlūk because of the Mongol invasions coming from the east and the Crusades from the west. The increase of scientific activity was caused not only by the coming of the scholars but also by the support given by the Mamlūk sultans. In fact, they built many new madrasas in addition to the resurrection of the old ones. In addition to madrasas during the Mamlūks period, mosque, hāngāh, ribat and zāwiya are also among the educational places.Hadith, fiqh and Tafsir scholar al-Zarkashī is originally Turkish. He was born in Cairo at 745 under the conditions mentioned above. His family learned of gold and silverworking because of their subsequent settlement to Egypt, and they made their living with this craft. A person who performs this is called Zarkash in Arabic. Muhammad ibn Bahādır, who learned and did this job, was known as al-Zarkashī. al-Zarkashī, known for his love of science since childhood, was trained hadith by Alā al-Dīn Mughultay (d. 762/1360) and Imād al-Dīn Ibn Kashīr (d. 774/1372) in Damascus, and fiqh by al-Asnawī (d. 772/1370). Among his beneficiaries are distinguished personalities such as al-Subkī (d. 756/1355), al-Azraī (d. 783/1381) and al-Bulqīnī (d. 824/1421). The most remarkable of his student is al-Birmāvī (d. 831/1428).It is known that he wrote about fifty works in hadith, tafsir, fiqh, methodology of fiqh and other fields. Especially among these works al-Burhān fī ʻUlūm al-Qur’ān, al-Tadhkira, al-Ijāba, al-Bahr al-Muhīt fî Usūl al-Fiqh ve al-Mansūr fī al-Qawāid is worth mentioning. Studies on al-Burhān and al-Bahr were carried out at the level of Master and PhD.al-Zarkashī did not hesitate to criticize any person for whom he had found his mistake. For example, even though he has a great love for him, and even because of this love, he has been given the name of al-Minhāj, the criticism of al-Nawawī is the clearest indication of the value given to science. Not just him, critics of scholars such as al-Hākim al-Naysābūrī and Ibn ʻAbd al-Barr who are recognized as authority in hadith can also be considered in this framework.The work named al-Tadhkira which we have studied in our work is of importance in that it shows the accumulation of knowledge in the field of hadith. In order to compose this work, it is necessary to have enough information in this field since the riwāyas must be criticized in terms of isnād and text. To compose his work, al-Zarkashī has benefited from about a hundred and forty works related to hadith, tafsir, al-siyar, history, tabakāt, commentary, jarh - taʻdīl, ilal and maghāzī. The use of such works is an effort to reach all sources and right information as much as possible. Some of these sources are basic hadith books such as al-Bukhārī (d. 256/870) al-Sahīh, Muslim (d. 261/875) al- Sahīh, Abū Dāʾūd (d. 275/889) al-Sunan, al-Tirmidhī (d. 279/892) al-Sunan, al-Nasā’ī (d. 303/915) al-Sunan, Ibn Mādja (d. 273/887) al-Sunan, Mālik ibn Anas (d. 179/795) al-Muwatta, Ahmad ibn Hanbal (d. 241/855) al-Musnad, al-Dārimī (d. 255/869) al-Sunan, ʻAbd al-Razzāq al-Sanʻānī (d. 211/826-27) al-Musannaf, Ibn Abī Shayba (d. 235/849) al-Musannaf, Ibn Rāhwayh (d. 238/853) al-Musnad, al- Bazzār (d. 292/905) al-Musnad, Abu Yaʻlā el-Mawsilī (d. 307/919) al-Musnad, Ibn Hibbān (d. 354/965) al-Sahīh, al-Tabarānī (d. 360/971) al-Muʻjam al-Awsat and al-Muʻjam al-Kabīr, al-Hākim al-Naysābūrī (d. 405/1014) al-Mustadrak.al-Zarkashī divided the riwāyas he had studied into eight subjects. These are judgments, wisdom, zuhd, medicine, virtue, prayer, story, words and riwāyas circulating in language. He shares the information he obtains from sources about him after mentioning the riwāyas he will examine. For example, it is mentioned that there is not a hadith which is transmitted as a hadith, it is a word of a sahāba, tābiun or a person. He transferred on the riwāyas the sources mentioned in the sources, but also stated that he did not participate in some information as the place came.The author has evaluated the narrators of the riwāyas from the point of jarh and taʻdīl. He did not only evaluate riwāyas in terms of isnād, but also text criticism. This activity is a distinctive feature of his work.al-Zarkashī gave information about the misrepresentation of the name of the narrators. He also explained the strange words that are difficult to understand in the text. It is a manifestation of his knowledge in the fiqh area that some of the riwāyas that are considered weak are expressed in some sects. The author described some errors about the riwāyas. For example, he stated that a riwāya that is said to be marfūʻ is a mavkūf. al-Zarkashī also included verses, hadiths and poems about the riwāya that he had studied while writing his work or he defended it by saying that it is not the case of a riwāya that is said to be fictitious.Perhaps it is the weakest point of al-Zarkashī’s work not to give any information about some riwāya, only to mention their isnāds. He also found some riwāyas that did not have a reliable isnāds and stated that their meanings are correct. This knowledge has become an enlightening characteristic for later generations.This work has a great significance in showing that the majority of the riwāyas that spread among the people are not hadiths. As a matter of fact, 73% of the riwāyas examined in the work are weak or irrelevant riwāyas. This work of al-Zarkashī is unique. The existence of such a work has not been determined before him. This work constituted the basis of the works written by scholars such as al-Sakhāwī and al-Aclūnī in the same subject after him. (shrink)

Güzellik ve sanat iç içe geçmiş iki kavramdır. Bir bakıma güzellik, sanatın özüdür denilebilir. Her sanat dalında olduğu gibi hat sanatında da güzeli arama arzusu ve eşsiz eserler ortaya koyma çabası, hattatları sabırla çalışmaya ve kendi sınırlarını zorlamaya sevk etmiştir. Bir kitap sanatı olan hüsn-i hattın kelime manasının “güzel yazı” olmasına mukabil, daha iyisini yazmak uğruna harcanan çaba yorucu ve zahmetlidir, ancak sabırla çalışan elbette ki karşılığını alır. Başka bir deyişle “Muhakkak ki Allah güzeldir, güzeli sever!” hadis-i şerifi ışığında bu (...) sanata gönül verenler, yazıyı daha muntazam yazma hususunda büyük ölçüde gayret gösterirler. Kişinin muntazam yazmayı başarması ise, sistematik çalışmasına bağlıdır. Yazıyı kaidelerine uygun ve ölçülü yazabilmek bıkmadan usanmadan, karamsarlığa kapılmadan çalışmakla mümkündür. Bu sebeple gerek öğrenme aşamasında ve gerekse sonrasında, harfler defalarca çalışma kâğıdına yazılarak el melekesi artırılır. Kelimeler ve harfler kâğıda kimi zaman noktalanıp ölçülendirilerek, kimi zaman da noktalanmadan yazılır. Talim amaçlı yapılan bu çalışmalar, başka bir deyişle karalamalar, hat sanatının temeli niteliğindedir. Arap alfabesiyle yazılan ve “karalama” adı verilen el alıştırmaları yazıyla uğraşan kişinin o an irticalen elinden çıkan harf veya kelimelerden oluşur ve çoğu zaman bir anlam ifade etmez. Bu çalışmanın amacı, karalamaların estetik unsurlarını ele almak ve zaman içerisinde uğradığı değişime mercek tutmaktır. Hattatların bu özgür yorumları gün geçtikçe daha fazla önemsenmekte ve hayranlık uyandırmaktadır. Harf bünyesini oluşturan kaidelerin dışında satır ve sınırlara bağlı kalmadan yazılan bu yazılar kendi içinde bir kompozisyon oluşturmakta ve çoğu zaman yazan kişiyi dahi hayrete düşürecek özgün çalışmalar ortaya çıkabilmektedir.

Researchers have raised concerns about teachers’ ability to embed nature of science in their science instruction, a complicated situation that is certainly impacted by the availability of adequate resources to assist K-12 science teachers. In light of the implementation of the ideas from the Framework for K-12 Science Education and the Next Generation Science Standards in the USA, this study sought to identify and evaluate resources aimed at guiding NOS instruction. A search of the National Science Teachers Association database for (...) Next Generation Science Standards -aligned instructional resources resulted in an analytical sample of eight lessons. All materials accompanying these lessons were analyzed for their representations of 10 NOS aspects. The evaluation of these materials revealed a prevalence of implicit, naïve representations in the sample lessons. Examination of the connections to NOS in these lessons leads to a set of recommendations to improve the quantity and quality of NOS representations in future NGSS-aligned instructional resources. The analytical approach used and the issues raised about the presentation and treatment of NOS in precollege lessons are of interest to the broader science education community. (shrink)

This article addresses a problematic interpretation of African and Indian decolonial political theory, arguing it understates the positive effects anticolonial ideas have had on society and scientific efforts to understand and produce knowledge about it. Another problem is its reliance on the concept of “Western” theory, which presumes genealogical purity. Our response offers creolization as an alternative model for decolonizing political theory and uses the term “Euromodern” instead. It then explores how creolization is at the heart of the ideas of (...) intellectuals considered most paradigmatic of Western thought, and demonstrates the influence of Afro-Islamic thought on them. Subsequently, we rebut the authors’ claim that Fanon’s thought has failed to generate new methods for studying postcolonial reality and extend their analysis of Indian society beyond the frames forged by Gandhi and Spivak. Finally, we conclude by discussing Muhammad Iqbal, a uniquely creolizing and forward-looking decolonial figure from the Afro-Muslim world. (shrink)

Topic of quantum chaos has begun to draw increasing attention in recent years. So, to ensure the security of digital image, an image encryption algorithm based on combining a hyperchaotic system and quantum 3D logistic map is proposed. This algorithm is applied in four stages. Initially, the key generator builds upon the foundation of mean for any row or column of the edges of the plain image. Its output value is used to yield initial conditions and parameters of the proposed (...) image encryption scheme. Next, it diffuses the plain image by the random sequences generated by 3D hyperchaotic system, and the diffusion process is realized by implementing XOR operation. Then, the diffused image and chaotic sequences are produced by the 3D quantum chaotic logistic map, expressed as a quantum superposition state using density matrix which is a representation of the state of a quantum system, and finally the resulting quantum image is then confused and diffused simultaneously by a unitary matrix generated by logistic chaos using XNOR operation to obtain the final cipher image. Because of the dependence on the plain image, the algorithm can frustrate the chosen-plaintext and known-plaintext attacks. Simulation results and theoretical analysis verify that the presented scheme has high safety performance, a good encryption effect, and a large key space. The method can effectively resist exhaustive, statistical, and differential attacks. Moreover, the encryption time of the proposed method is satisfactory, and the method can be efficiently used in practice for the secure transmission of image information. (shrink)

Fractional calculus is nowadays an efficient tool in modelling many interesting nonlinear phenomena. This study investigates, in a novel way, the Ulam–Hyers and Ulam–Hyers–Rassias stability of differential equations with general conformable derivative. In our analysis, we employ some version of Banach fixed-point theory. In this way, we generalize several earlier interesting results. Two examples are given at the end to illustrate our results.

This commentary is a critical appraisal of Gil-Pérez et al.'s (2002) conceptualization of constructivism. It is argued that the following aspects of their presentation are problematic: (a) Although the role of controversy is recognized, the authors implicitly subscribe to a Kuhnian perspective of `normal' science; (b) Authors fail to recognize the importance of von Glasersfeld's contribution to the understanding of constructivism in science education; (c) The fact that it is not possible to implement a constructivist pedagogy without a constructivist epistemology (...) has been ignored; and (d) Failure to recognize that the metaphor of the `student as a developing scientist' facilitates teaching strategies as students are confronted with alternative/rival/conflicting ideas. Finally, we have shown that constructivism in science education is going through a process of continual critical appraisals. (shrink)

The current study aimed at identifying the awareness level of artificial intelligence applications' risks among faculty members and its relation to the attitude towards digital culture at Imam Abdulrahman Bin Faisal University. The descriptive survey method was used. A questionnaire was designed to measure the awareness of the artificial intelligence applications' risks, and a scale for measuring the attitude towards digital culture. They were administered to a sample of [463] faculty members at Imam Abdulrahman Bin Faisal University. The study concluded (...) that there is an average awareness of the artificial intelligence applications' risks and the attitude towards digital culture among faculty members. A significant relationship was found out between awareness of the artificial intelligence applications' risks as a whole and the attitude towards digital culture. The results indicated that there are no differences in the awareness level of the artificial intelligence risks due to the variables of: gender, use duration of digital applications, and colleges. There are no differences in the variable of the attitude towards digital culture with its various dimensions: cognitive, psychomotor, and affective and its total score. The current study recommended designing a professional development plan for faculty members on the negative effects and risks of artificial intelligence, and launching an Arab platform based on artificial intelligence applications.

Research on the nature of science and science education enjoys a longhistory, with its origins in Ernst Mach's work in the late nineteenthcentury and John Dewey's at the beginning of the twentieth century.As early as 1909 the Central Association for Science and MathematicsTeachers published an article – ‘A Consideration of the Principles thatShould Determine the Courses in Biology in Secondary Schools’ – inSchool Science and Mathematics that reflected foundational concernsabout science and how school curricula should be informed by them. Sincethen (...) a large body of literature has developed related to the teaching andlearning about nature of science – see, for example, the Lederman and Meichtry reviews cited below. As well there has been intensephilosophical, historical and philosophical debate about the nature of scienceitself, culminating in the much-publicised ‘Science Wars’ of recent time. Thereferences listed here primarily focus on the empirical research related to thenature of science as an educational goal; along with a few influential philosophicalworks by such authors as Kuhn, Popper, Laudan, Lakatos, and others. Whilenot exhaustive, the list should prove useful to educators, and scholars in otherfields, interested in the nature of science and how its understanding can berealised as a goal of science instruction. The authors welcome correspondenceregarding omissions from the list, and on-going additions that can be made to it. (shrink)

This study focused on the identification problems of two-input single-output system with moving average noises based on unsupervised learning methods applied to the input signals. The input signal to the autoregressive moving average model is proposed to be arriving from a source with continuous technical and environmental changes as two separate featured input signals. These two input signals were grouped in a number of clusters using the K-means clustering algorithm. The clustered input signals were supplied to the model in an (...) orderly fashion from cluster-1 up to cluster-K. To ensure that the output signal can be best predicted from the input signal which in turn leads to selecting good enough model for its intended use, the magnitude-squared coherence measure is applied to the input/output signals in the cases of clustered and nonclustered inputs, which indicates best correlation coefficient when measured with clustered inputs. From collected input-output signals, we deduce a K-means clustering based recursive least squares method for estimating the parameter of autoregressive moving average system. The simulation results indicate that the suggested method is effective. (shrink)

Stemming from the realization of the importance of the role of explanation in the science classroom, the Next Generation Science Standards call for appropriately supporting students to learn science, argue from evidence, and provide explanations. Despite the ongoing emphasis on explanations in the science classroom, there seems to be no well-articulated framework that supports students in constructing adequate scientific explanations, or that helps teachers assess student explanations. Our motivation for this article is twofold: First, we think that the ways in (...) which researchers in science education have studied scientific explanation are, at best, leaves much to be desired and, at worst, simply incomplete. Second, we believe that research about the teaching and learning of explanation in science classrooms must be guided by explicit models or frameworks that specify elements involved in constructing explanations particularly applicable to science. More importantly, we think that the development of such models or guidelines should be based on theoretical and philosophical foundations. In order to develop these frameworks or guidelines, we first outline and clarify models of scientific explanation developed by philosophers of science over the last few decades. In the second section of this article, we present a more recent philosophical work on scientific explanation, the pragmatic approach to studying scientific explanations. This approach suggests a toolbox for analyzing scientists’ scientific explanations, which provides a useful instrument to science education. In Section 3, we discuss the ways by which the previous two sections are useful in developing a K-12 scientific explanation schema. Implications for future research on students’ explanations are discussed. (shrink)

In this paper, I analyse the issue of “hadith fatwas”, which has not studied enough in academic ground. The litera-ture of hadith fatwas is consisted of the questions asked by all Muslims, whether they have academic interest in Hadith or not, to the scholars and the answers given by the scholars. The most famous samples of this literature, which dates back to 3rd century AH, were written in the 9th and 10th century AH. One of the most distinguishing features of (...) this genre is that it addresses all Muslims. Various modern works can be included in this literature, which are similar to hadith fatwas in terms of the form and the audience addressed by them. However, the works of the pre-modern and modern eras differ in the sense of the questions and the answers. In order to introduce this genre and compare between its samples in two different eras, I examine the works of as-Sahawi, as-Suyuti, Ahmet Yücel and Yavuz Köktaş. In this study, I focus on writers’ wording and method, sources and content of subjects of fatwas. (shrink)
