Narrated `Aisha: Aflah, the brother of Abi Al-Quais, asked permission to visit me after the order of Al-Hijab was revealed. I said, I will not permit him unless I take permission of the Prophet about him for it was not the brother of Abi Al-Qu'ais but the wife of Abi Al-Qu'ais that nursed me. The Prophet entered upon me, and I said to him, O Allah's Messenger ! Allah, the brother of Abi Al-Qu'ais asked permission to visit me but I refused to permit him unless I took your permission. The Prophet said, What stopped you from permitting him? He is your uncle. I said, O Allah's Messenger ! The man was not the person who had nursed me, but the woman, the wife of Abi Al-Qu'ais had nursed me. He said, Admit him, for he is your uncle. Taribat Yaminuki (may your right hand be saved) `Urwa, the sub-narrator added: For that `Aisha used to say, Consider those things which are illegal because of blood relations as illegal because of the corresponding foster relations.
