The Holy Prophet (S) had married her before his proclamation...

The Holy Prophet (S) had married her before his proclamation of prophethood and before command arrived not to give daughters to infidels, to Abil Aas bin Rabia, from whom Amamah binte Abil Aas was born and Amirul Momineen (a.s.) married her after the passing away of Lady Fatima Zahra, according to the bequest of Fatima. After the martyrdom of Imam Ali (a.s.) Amama married Mughaira bin Naufal bin Harith bin Abdul Muttalib.

And Ibn Babawayh has narrated through authentic chains of narrators that Amama binte Abul Aas was born from Zainab, after the passing away of Fatima Zahra (s.a.), married Amirul Momineen (a.s.) and after his martyrdom she became the wife of Mughaira bin Naufal. After that she was struck with a serious illness and she became dumb. Imam Hasan and Imam Husain (a.s.) came to her when she could not speak. They told her to make her bequest, but Mughaira didn’t want her to make a bequest.

Imam Hasan and Imam Husain (a.s.) asked her: “Would you like to emancipate so and so slave?” She gestured positively. Then they asked if such and such action may be performed on her behalf. She nodded in assent and in this way she made her bequest and authorized the two Imams to carry out her will after her death.

It is narrated that when Abul Aas was taken as a prisoner in the Battle of Badr, Zainab brought her slave who was given to her by Lady Khadija as a ransom to the Prophet for her husband. When the Holy Prophet (S) saw him, he was reminded of Lady Khadija and he began to weep. So he requested the companions to forgo the ransom and release Abul Aas without ransom.

complied with his request and the Holy Prophet (S) released him with the condition that when he goes back to Mecca he will send Zainab to the Prophet. He fulfilled his promise and sent Zainab. Then he also came to Medina and embraced Islam as was mentioned in brief before. According to one report Zainab passed away in 7 A.H. and according to another report in 8 A.H.

The second daughter, Ruqaiyyah, was said to be betrothed to Atba bin Abu Lahab, but she was divorced before the consummation of marriage; she afterwards married Uthman at Medina. A son, Abdullah was born to her but he died in childhood. Ruqaiyyah died in Medina at the time of the Battle of Badr. The third daughter was Umm Kulthum and she was also married to Uthman.
