He said “Do you like that?” she said “I am not alone with you of those who share me in this good, my sister is most to my liking. He said “She is not lawful for me.” She said “By Allaah, I was told that you were going to betroth with you Darrah to Durrah , the narrator Zuhair doubted the daughter of Abu Salamah. He said “The daughter of Umm Salamah? She said “Yes”. He said “(She is my step daughter). Even if she had not been my step daughter under my protection, she would not have been lawful for me. She is my foster niece (daughter of my brother by fosterage). Thuwaibah suckled me as well as his father (Abu Salamah). So do not present to me your daughters and your sisters.
