Narrated `Aisha:Allah, the brother of Abu Al-Qu'ais asked my permission to enter after the verses of Al-Hijab (veiling the ladies) was revealed, and I said, "By Allah, I will not admit him unless I take permission of Allah's Apostle for it was not the brother of Al-Qu'ais who had suckled me, but it was the wife of Al-Qu'ais, who had suckled me." Then Allah's Messenger (ﷺ) entered upon me, and I said, "O Allah's Messenger (ﷺ)! The man has not nursed me but his wife has nursed me." He said, "Admit him because he is your uncle (not from blood relation, but because you have been nursed by his wife), Taribat Yaminuki." `Urwa said, "Because of this reason, ' Aisha used to say: Foster suckling relations render all those things (marriages etc.) illegal which are illegal because of the corresponding blood relations." (See Hadith No. 36, Vol. 7)

Sahih
'Urwa related that 'A'isha said, "Aflah, the brother of Abu'l-Qu'ays, asked permission to visit me after the Veil was revealed. I said, 'By Allah, I will not give him permission until I ask the Prophet, may Allah bless him and grant him peace, for permission for him. It was not his brother, Abu'l-Qu'ays, who nursed me. It was the wife of Abu'l-Qu'ays who nursed me.' The Prophet, may Allah bless him and grant him peace, visited me and I said to him, 'Messenger of Allah, Aflah, the brother of Abu'l-Qu'ays, asked permission to visit me, but I refused to give him permission until I had asked for your permission.' The Prophet, may Allah bless him and grant him peace, said, 'What stops you from giving permission to your uncle?' I said, 'Messenger of Allah, the man is not the one who nursed me. It was his wife who nursed me.' He said, 'Admit him. He is your uncle, may your right hand be dusty!'" 'Urwa said, "That is why 'A'isha used to say, "Suckling makes inviolable that which lineage makes inviolable."
