5107. Narrated Umm Ḥabība: I said, "O Allāh's Messenger! Marry my sister, the daughter of Abū Sufyān." He said, "Do you like that?" I said, "Yes, for even now I am not your only wife; and the most beloved person to share the good with me is my sister." The Prophet ﷺ said, "But that is not lawful for me (i.e., to be married to two sisters at a time.)" I said, "O Allāh's Messenger! By Allāh, we have heard that you want to marry Durra, the daughter of Abū Salama." He said, "You mean the daughter of Umm Salama?" I said, "Yes." He said, "By Allāh! Even if she were not my step-daughter, she would not be lawful for me to marry, for she is my foster niece, for Thuwaiba has suckled me and Abū Salama; so you should neither present your daughters nor your sisters to me."
