Mahdism (Arabic:المهدوية,romanized: al-Mahdawiyya), in theTwelver branch ofShia Islam, is derived from the belief in the reappearance of the Twelfth ShiiteImam,Muhammad al-Mahdi, as thesavior of theapocalypse for the salvation of human beings and the establishment of peace and justice. Mahdism is a kind ofmessianism. From this perspective, it is believed thatJesus andKhidr are still alive and will emerge with Muhammad al-Mahdi in order to fulfil their mission of bringing peace and justice to the world.^[1][2][3]

Many verses of theQuran are related to Mahdism,^[4][5] such as verse 105 ofAl-AnbiyaSurah:

«وَ لَقَدْ کَتَبْنَا فیِ الزَّبُورِ مِن بَعْدِ الذِّکْرِ أَنَّ الْأَرْضَ یَرِثُهَا عِبَادِیَ الصَّالِحُون»
"Certainly We wrote in the Psalms, after the Torah: ‘Indeed My righteous servants shall inherit the earth’."

The commentators have considered the fulfillment of the promise mentioned in the verse at the time of thereappearance ofImam Muhammad al-Mahdi.^[6][7] Also, verse 5 ofAl-Qasas Surah:

«وَ نُرِیدُ أَن نَّمُنَّ عَلیَ الَّذِینَ اسْتُضْعِفُواْ فیِ الْأَرْضِ وَ نجَعَلَهُمْ أَئمَّةً وَ نجَعَلَهُمُ الْوَارِثِین»
"And We desired to show favour to those who were abased in the land, and to make them imams, and to make them the heirs"

Some have considered the interpretations of this verse to be related toMuhammad al-Mahdi^[8][9] and others have considered it to be related to the return (Rajʽa) of theImams and the return of the government to them.^[10][11][12] Verse 55 of SurahAn-Nur:

«وَعَدَ اللَّهُ الَّذِینَ ءَامَنُواْ مِنکمُ وَ عَمِلُواْ الصَّلِحَتِ لَیَسْتَخْلِفَنَّهُمْ فیِ الْأَرْضِ کَمَا اسْتَخْلَفَ الَّذِینَ مِن قَبْلِهِمْ وَ لَیُمَکِّنَنَّ لهُمْ دِینهَمُ الَّذِی ارْتَضیَ لهَمْ وَ لَیُبَدِّلَنهُّم مِّن بَعْدِ خَوْفِهِمْ أَمْنًا یَعْبُدُونَنیِ لَا یُشْرِکُونَ بیِ شَیْا وَ مَن کَفَرَ بَعْدَ ذَالِکَ فَأُوْلَئکَ هُمُ الْفَاسِقُون»
"Allah has promised those of you who have faith and do righteous deeds that He will surely make them successors in the earth, just as He made those who were before them successors, and He will surely establish for them their religion which He has approved for them, and that He will surely change their state to security after their fear, while they worship Me, not ascribing any partners to Me. Whoever is ungrateful after that—it is they who are the transgressors"

Also it is known to be related to Mahdism issues. Some have considered the fulfillment of the promise mentioned in the verse at the time of the reappearance of the Twelfth Imam, Muhammad al-Mahdi^[13] and some have considered the community mentioned in the verse to be achievable only at the time of the reappearance of Muhammad al-Mahdi.^[14]

TheShiites of theTwelver branch ofShia Islam believe that according to the divine promise, a descendant ofMuhammad, Prophet of Islam or his namesake, the ninth child of the descendants ofHusayn ibn Ali, willappear with the epithet of "Mahdi"^[17] and will spread justice throughout the earth.^[18]

According to this belief,Mahdi, the son ofHasan al-Askari (the eleventh Shiite Imam), was born in 870 CE. Upon the death of his father, while he was still a child, after the early years of hisImamate, he disappeared and would only contact his followers through hisfour successive deputies.^[19][20] The period of the so-calledminor occultation or first occultation, in which Mahdi was not in direct contact with the people, only through his special deputies,^[21] which was mostly in contact with the Shiites. According to official tradition, in 940 CE, the fourth and last delegate received a final letter signed by the hidden Imam in which he declared that henceforth and "until the end of time," no one will see him or be his representative, and that whosoever declares otherwise is no less than an imposter. Thus a long absence began, the so-calledmajor occultation or second occultation.^[20]

Some late Shiite scholars who have questioned or rejecting Mahdism includeAbolfazl Borqei Qomi,^[22][23] Heidar Ali Qalmadaran Qomi, andMohammad Hassan Shariat Sanglaji.^[24]

Among the present scholars who have worked on Mahdism isLotfollah Safi Golpaygani. He has two important works in this field,Selected Trace About the Twelfth Imam^[25][26] andImamate and Mahdism^[27][28]).^[29][30]

One of the events that spread the idea of Mahdism was the sudden death ofIsmail, the son ofJa'far al-Sadiq (the sixth Imam of the Shiites), in 762 CE, who, according to theIsma'ilism Shiites, had previously been appointed as the seventh Imam of the Shiites. Although most Shiites gathered around Ja'far al-Sadiq's other son,Musa al-Kadhim, a minority of Shiites did not accept Ismail's death, claiming that Ismail was still alive and hiding himself. According to them, Ismail is the absent Imam.^[31] With the rise of theFatimid Caliphate inEgypt, the epithet of "Mahdi" was attributed to the first Fatimid caliph and his successors, citing hadiths narrated by theIsma'ilists and other sources. However, the Isma'ilists expect the seventh Isma'ili Imam to appear under the name ofQa'im at the end of time.^[32]

In theZaidi Shi'ism sect, who do not consider the Imams to have superhuman powers, belief in Mahdism is very inconspicuous. Throughout history, many people have beenconsidered as "Mahdi" or claimed to be alive and absent. One of them wasHusayn ibn Qasim Ayani, the leader of a sect branching out fromZaidi Shi'ism, called the Husaynieh sect. A group denied his death and claimed him as "Mahdi" and believed that he wouldreturn. But this beliefs about these people is not recognized by theZaidi Shi'ism majority.^[32]

According toReza Aslan, with the development of the Mahdism doctrine among the Shiites,Sunnijurisprudence scholars tried to distance themselves from belief in the Mahdi.^[31] According toWilferd Madelung, despite the support of belief in the Mahdi by some important Sunnitraditionists, belief in the Mahdi has never been considered as one of the main beliefs of Sunni jurisprudence. The Mahdi is mentioned in Sunni beliefs, but rarely. Many prominent Sunni scholars, such asAl-Ghazali, have avoided discussing this issue. Of course, according to Madelung, this avoidance was less due to disbelief in the Mahdi^[32] and more (according to Reza Aslan) due to wanting to avoid disputes and social riots.^[31][32]

There are exceptions such asIbn Khaldun in the book "Muqaddimah" who openly opposes belief in the Mahdi and considers allhadiths related to the Mahdi to be fabricated. There are different views among the traditionists and scholars who have dealt with the Mahdism issue. The epithet of "Mahdi" has been mentioned many times in the book "Musnad" byAhmad ibn Hanbal (founder of theHanbalischool of Sunni jurisprudence — one of the four major orthodox legal schools ofSunni Islam, and also one ofthe four Sunni Imams) and various hadiths about the signs of the reappearance of the "Promised Mehdi" (and Jesus in his cooperation) mentioned there. Ahmad ibn Hanbal has narrated in his work that:

Sufyan ibn ʽUyaynah fromAasim ibn Abi al-Najud, narrated a hadith fromAbdullah ibn Masud [acompanion of the Islamic prophetMuhammad] from the Prophet Muhammad:
«لا تقوم الساعة حتی یلی رجل من اهل بیتی، یواطی ء اسمه اسمی.»
"The resurrection will not take place until a man from my family namesake with me emerges."^[33]

In mentioning the importance and validity of Ahmad ibn Hanbal's "Musnad" among the Sunnis, it is enough thatTaqi al-Din al-Subki writes on page 201 of the first volume of "Tabaqat al-Shafeiyah":^[34]

"Ahmad ibn Hanbal's Musnad is one of the basis of Muslim beliefs"

AlsoAl-Suyuti, a Sunni Egyptian Muslim scholar, has discussed the validity of Ahmad ibn Hanbal among Sunnis in the introduction to the book "Jam al-Javameh".^[35]Ali ibn Abd-al-Malik al-Hindi, the author ofKanz al-Ummal, says in that book:

«کل ما فی مسند احمد حنبل فهو مقبول»
"What is in the book "Musnad" of Ahmad ibn Hanbal is accepted by the Sunnis."^[36]

In some hadiths in Sunni books, "Mahdi" is the same as "Jesus Christ", while in other narrations there is no mention of the identity of that person, or it is said that "he rises with Jesus." The Mahdi is also mentioned as one of the descendants ofHusayn ibn Ali, the descendants ofHasan ibn Ali or the son ofHasan al-Askari, the twelfth Imam of Shiites.^[32] Throughout history to the present day, there have been long debates among Sunni scholars about the "savior" role and the "political" role of the Mahdi.^[31]

But according toSeyyed Hossein Nasr, the Sunnis believe that the Mahdi is from the family of Muhammad, the Prophet of Islam and will emerge with Jesus in the end times. He also writes that the belief in the coming of the Mahdi is so strong among Muslims that throughout history, especially in times of pressure and hardship, has led to the emergence of claimants of "Mahdism".^[37] Contemporary Sunni writers such asAbd al-Muhsin al-Ibad,Muhammad Ali al-Sabuni, andAbd al-Aziz ibn Baz have also referred to the hadiths attributed to the Prophet of Islam about the Mahdi and the savior of the end times in their books and speeches, and have considered these hadiths trustworthy because have been mentioned frequently by different narrators.^[38][39][40]

According toDenise Spellberg, the concept of "Mahdism", although not one of the main Sunni beliefs, has been considered by Sunnis throughout history. In 1881,Muhammad Ahmad claimed to be the Mahdi inSudan and startedan uprising that was suppressed in 1898 by British forces. Belief in Mahdism spurred uprisings in the west and north ofAfrica in the nineteenth century. In 1849, a person namedBo Zian led an uprising inAlgeria against the French tax system and the occupation of his country by the French under the name of Mahdi.^[41]

Abdolkarim Soroush is one of the few thinkers who has analyzed the relationship between Mahdism and politics and presented a new perspective on Mahdism. He believes that political Mahdism has historically manifested itself in politics in at least four ways:^{[42][43][44][45]}

• The theory ofGuardianship of the Islamic Jurist: The theory of Guardianship of the Islamic Jurist, which is incompatible withdemocracy, is the child of political Mahdism. Political Mahdism justifies the special privileges ofFaqīhs for government in the theory of Guardianship of the Islamic Jurist. Political Mahdism, based on the theory of Guardianship of the Islamic Jurist, presupposes the "supremeFaqīh" as the deputy ofMuhammad al-Mahdi and gives the same authority to the "supreme Faqīh" in power and possession of the properties of the Muslims population, that the absent Imam has.
• The theory of monarchy on behalf of the Imam of theSafavid kings: Another form of political Mahdism throughout history thatAbdolkarim Soroush refers to has been the theory of "monarchy on behalf of the Imam of the Safavid kings." This theory was in fact the political theory of the Safavids. This theory is also clearly in conflict with democracy.
• Hojjatieh's theory of political impracticality: Another form of political Mahdism mentioned byAbdolkarim Soroush is the theory of political impracticality during the absence and condemn all the governments before the emerge of the "Imam of Time" as usurper. Throughout history, many Shiite Faqīh have advocated this theory, and before the Islamic Revolution, this view was propagated by theHojjatieh Association.
• The theory of revolutionary Islam or the "Waiting, a protest school": According toAbdolkarim Soroush, another form of Mahdism that is not very compatible with democracy is the theory of "Waiting, a protest school" by Dr.Ali Shariati. Shariati appears in the article "Waiting, a protest school" as a utopian and historian who believes in the determinism of history, who has a pragmatic approach to waiting for Mahdism to change the current status and achieve his desired utopia.
