It was narrated from Umm Habibah that she said:

"O Messenger of Allah, what do you think of my sister?" He said: "What for?" She said: "For marriage." He said: "Would you like that?" She said: "Yes; I do not have you all to myself, and I would like to share this goodness with my sister." He said: "She is not permissible for me (to marry)." She said: "But I heard that you want to marry Durrah, the daughter of Umm Salamah." He said: "The daughter of Umm Salamah?" She said: "Yes." He said: "By Allah, even if she were not my stepdaughter she would not be permissible for me (to marry), because she is the daughter of my brother through breastfeeding. Do not offer your daughters and sisters to me in marriage."
