Yahya related to me from Malik from Ibn Shihab from Qabisa ibn Dhu'ayb that a man asked Uthman ibn Affan whether one could have intercourse with two sisters who one owned. Uthman said, "One ayat makes them halal, and one ayat makes them haram. As for me, I wouldn't like to do it." The man left him and met one of the companions of the Messenger of Allah, may Allah bless him and grant him peace, and asked him about it, and he said, "Had I any authority and I found someone who had done it, I would punish him as an example."

Ibn Shihab added, "I think that it was Ali ibn Abi Talib. "

← Previous Hadith Yahya related to me from Malik from Ibn Shihab from Ubaydullah ibn Abdullah ibn Utba ibn Masud from his father that Umar ibn al- Khattab was asked about a woman and her daughter who were in the possession of the right hand, and whether one could have intercourse with one of them after the other Umar said, "I dislike both being permitted together." He then forbade that.

Muwatta Malik Book 28, Hadith 35 Next Hadith → Yahya related to me from Malik that he had heard that az-Zubayr ibn al-Awwam said the like of that.

Malik said that if a man had sexual relations with a female slave that he owned, and then he wanted to also have relations with her sister, the sister was not halal for a man until intercourse with the slave-girl had been made haram for him by marriage, setting free, kitaba, or the like of that - for instance, if he had married her to his slave or someone other than his slave.
