Umm Habibah (may Allah be pleased with her), the wife of the Prophet (peace and blessings be upon him), said: O Messenger of Allah! Marry my sister, the daughter of Abu Sufyan. The Messenger of Allah (peace and blessings be upon him) said to her: "Would you like that?" She said: I am not the only one with a claim on you, and my sister is the best one to share with me in this good. He (peace and blessings be upon him) said: "That is not permissible for me." She said: By Allah! We are saying that you wish to marry Durrah bint Abi Salamah. He (peace and blessings be upon him) said: "The daughter of Umm Salamah?" She said: Yes. He (peace and blessings be upon him) said: "By Allah! Even if she were not my stepdaughter, she would still not be lawful for me; she is the daughter of my foster brother. Thuwaybah nursed both me and her. So do not offer me your daughters or your sisters."
