Sayyida Zaynab bint Umm Salamah (may Allah be pleased with her) narrates: Sayyida Umm Habibah (may Allah be pleased with her) said: O Messenger of Allah (peace and blessings be upon him)! Marry the daughter of Abu Sufyan. She said this regarding her sister, so the Prophet (peace and blessings be upon him) said: Do you like this? She replied: Yes, I wish that my sister also shares with me in this goodness. The Prophet (peace and blessings be upon him) said: This is not permissible. Sayyida Umm Habibah (may Allah be pleased with her) said: O Messenger of Allah (peace and blessings be upon him)! By Allah! We have been told that you want to marry Durrah, the daughter of Abu Salamah. The Prophet (peace and blessings be upon him) asked: With the daughter of Abu Salamah? Sayyida Umm Habibah (may Allah be pleased with her) replied: Yes. The Prophet (peace and blessings be upon him) said: If she were not my stepdaughter, even then she would not be lawful for me, because she is the daughter of my foster brother. Thuwaibah nursed both me and Abu Salamah. Do not present the proposals of your daughters and sisters before me.
