There are manyBiblical figures which theQur'an names. Some, however, go unnamed in theQur'an, but are referenced or referred to in thehadiths,tafsirs, literature orseerah. Other figures are mentioned elsewhere in tradition and in thesunnah and sayings ofMuhammad. Such figures which are not mentioned by name in theQur'an, are included below.

Cain and Abel (Arabic:هابيل,قابيل;Qābīl and Hābīl) are believed byMuslims to have been the first two sons ofAdam andEve. The story in theQur'an[1] is virtually the same as theHebrew Bible narrative, saying that both the brothers were asked to offer up individual sacrifices toGod. God accepted Abel's sacrifice because of Abel's righteousness and Cain, out of jealousy, slew Abel. This was the first ever sin committed upon Earth but Abel was chronicled in history as one of the first believers and as the first evermartyr. A handful of Muslim sources have identified Abel as a prophet like his father, but this identification is not traditional.[2]
Of Adam's first children, Cain was the elder son and Abel the younger. Each of them presented a sacrifice toGod but it was accepted only from Abel, because of the latter's righteous attitude and his faith and firm belief inAllah.
After the offering of their sacrifices, Cain, the wicked sibling, taunted Abel out of envy and told him that he would surely slay him. Abel justly warned Cain thatGod only accepted the sacrifice of those that are righteous in their doings. He further went onto tell Cain that if Cain did indeed try to slay him,[3] Abel would not retaliate and slay him because the God-fearing would never murder for the sake of envy. Abel then told Cain that in murdering him, he would carry the weight not only of his sin but also of the sins of his victim[4] The victim, as a result, in suffering the injustice, would be forgiven his own sins and the murderer, while being warned, would consequently increase his own sin. Abel preached powerfully and reminded Cain that the punishment for murder would be that he would spend the afterlife in the fires ofHell.
The innocent pleading and preaching of Abel had no effect upon Cain, for he was full of arrogance, pride and jealousy. He subsequently slew[5] the righteous Abel, but in doing so, he ruined himself and became of those who remain lost. This would be the earliest example of the murder of a righteous man taking place upon the earth. In the future, many other evildoers would slay the wise and pious believers.
Right after the murder took place,God sent a raven who scratched the ground to show Cain how to bury the bodies of the deceased. Cain, in his shame, began to curse himself[6] and became full of guilt. He at last realized how dreadful it was to slay anyone, the more so as the victim was an innocent and righteous man, as well as his brother. Full of regrets, Cain was marked with deep sorrow. This was, however, no true repentance.
God makes it clear in theQur'an that the story of Cain and Abel was a message[7] for theChildren of Israel (who habitually murdered their prophets as stated inSurah Al-Baqara2:87), as it had told them about the consequences of murder and that the killing of one person would be as if they had slain the whole of mankind. But still people rejected the message of the story and continued to commit grave sins, slaying prophets and messengers as well as the righteous people.
All the prophets who preached since the time ofAdam were persecuted, insulted or reviled in one way or another. With some righteous men, however, the evildoers went one step further, in attempting to slay them or indeed slaying them. The Qur'an itself mentions the slaying of the righteous, saying inSurah Al Imran3:21 "As to those who deny the Signs of Allah and in defiance of right, slay the prophets, and slay those who teach just dealing with mankind, announce to them a grievous penalty".[8] Historical examples of the righteous being slain includeZakariyya (Zechariah) and his sonYahya (John).

Sarah (Arabic:سارة,Sāra), the wife of thepatriarch andIslamic prophetIbrāhīm (Abraham) and the mother of theprophetIshaq (Isaac) is an honoured woman in theIslamic faith. According toMuslim belief, she was Abraham's first wife. Although not mentioned by name in theQur'an, she is referenced and alluded to via the story of her husband. She lived with Abraham throughout her life and, although she was barren,God promised her the birth of a prophetic son and a prophetic grandson by the name ofYa`qūb (Jacob).
Sarah and Abraham had no children. Abraham, however, prayed constantly to God for a son. Sarah, being barren, subsequently gave him herEgyptianhandmaiden,[9]Hājar (Hagar), to wed as his second wife. Hagar boreIsmā'īl (Ishmael), when Abraham was 86,[10] who too would become a prophet of God like his father.
Thirteen years later, God announced to Abraham, now a hundred,[11] that the barren Sarah would give birth to his second son, Isaac, who would also be a prophet of the Lord. Although the Qur'an does not mention Sarah by name, it vividly mentions the annunciation of the birth of Isaac. The Qur'an mentions that Sarah laughed when the angels gave her the glad tidings of Isaac, which is perhaps why the name Isaac (in ArabicIshaq) has the root meaning of 'laughter'.[12]
There came Our messengers to Abraham with glad tidings. They said, 'Peace!' He answered, 'Peace!' and hastened to entertain them with a roasted calf.
But when he saw their hands went not towards the (meal), he felt some mistrust of them, and conceived a fear of them. They said: "Fear not: We have been sent against the people ofLut.
And his wife was standing (there), and she laughed: But we gave her glad tidings of Isaac, and after him, of Jacob.
She said: "Alas for me! shall I bear a child, seeing I am an old woman, and my husband here is an old man? That would indeed be a wonderful thing!"
Sarah is believed by Muslims to be buried in theCave of the Patriarchs (known by Muslims as theSanctuary of Abraham). The compound, located in the ancient city ofHebron, is the second holiest site forJews (after theTemple Mount inJerusalem), and is also venerated byChristians and Muslims, both of whom have traditions which maintain that the site is the burial place of three Biblical couples: Abraham and Sarah, Isaac andRebecca, and Jacob andLeah. Although Jews alternatively also believe this to be the burial place forAdam andEve, this is a view not usually adopted by Muslims.

In regards toBalaam in Islam, it is very doubtful whether there is any reference to Balaam in theQur'an. Old classical commentators applied to him, but with reservations:
Relate to them the story of the man to whom We sent Our signs, but he passed them by: so Satan followed him up, and he went astray.
If it had been Our will, We should have elevated him with Our signs; but he inclined to the earth, and followed his own vain desires. His similitude is that of a dog: if you attack him, he lolls out his tongue, or if you leave him alone, he (still) lolls out his tongue. That is the similitude of those who reject Our signs; So relate the story; perchance they may reflect.
Many modern commentators, includingAbdullah Yusuf Ali, however, feel that the tale of Balaam was different and unrelated.
Ibn Kathir considersJeremiah (Arabic:أرميا,Armaya) to be a prophet ofIslam, though he is not mentioned in the Qur'an; in his bookStories Of The Prophets, places Jeremiah in the prophetic pantheon, alongside fellowOld Testament prophetsDaniel,Ezekiel andIsaiah. Scholars believe that Jeremiah was a descendant ofLevi, son ofJacob, and lived at a troubled time when there were many false prophets spreading false messages.

Danyal (Arabic:دانيال), known as Daniel in theBible, is traditionally considered byIbn Kathirs to be aprophet, alongside the othermajor prophets of theOld Testament, namelyIsaiah,Jeremiah andEzekiel. Although he is not mentioned in theQur'an, there are a fewHadith[which?] which bear his name and which refer to his time spent in the den of the lions.[citation needed] There are debates, however, that go on about Daniel's time of preaching and some Muslims believe that he was not a prophet but instead a saintly man.
It was he who preached in Babylonian 'Iraq, exhorting the people to return toGod. He lived during the reign ofCyrus, and taught this prince the unity of God and the true religion.Al-Tabari says ("Chronique," French translation ofZotenberg, i. 44) that thousands of people who had died in a certain town from an epidemic were resuscitated a thousand years later by the prayer of Daniel.[15]
When Daniel had become a noted prophet, Cyrus made him the chief of all his kingdom in order that he might teach his people the true religion. Daniel asked the king to let him go back toIsrael and re-build theTemple orBayt Ha-Mikdash in Hebrew. Cyrus consented to thereconstruction of the sanctuary, but refused to let him go, saying, "If I had a thousand prophets like thee, I should have them all stay with me". There is another tradition, to the effect that Daniel was king of theIsraelites after their return from captivity.
