And with the same chain of narration, it is narrated that (Urwah bin Zubair) was informed by Sayyidah Aisha (may Allah be pleased with her): The brother of Abu Al-Qais, named Aflah, who was a foster uncle of Sayyidah Aisha (may Allah be pleased with her), sought permission to come to me after the obligation of hijab (veil) had been revealed. I refused to grant him permission. When the Messenger of Allah (peace and blessings be upon him) arrived, I informed him of what I had said. He (peace and blessings be upon him) instructed me to allow him to enter.

And with this same chain (it is narrated from Sayyida Aisha, may Allah be pleased with her) that my foster uncle came and asked permission to enter (the house), but I refused to give him permission so that I could ask the Messenger of Allah, peace and blessings be upon him. Then when the Messenger of Allah, peace and blessings be upon him, came, I asked him about this matter. He, peace and blessings be upon him, said: "He is your uncle, allow him." I said: O Messenger of Allah! It was the woman who suckled me, not the man. The Messenger of Allah, peace and blessings be upon him, said: "He is your uncle, he may come to you." Aisha, may Allah be pleased with her, said: This was after the command of veiling was revealed to us. And Aisha, may Allah be pleased with her, said: The relationships that are forbidden by lineage are also forbidden by suckling.

It is narrated from Umm al-Mu'mineen Sayyida Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) was with her when she (Aisha, may Allah be pleased with her) heard the voice of a man who was seeking permission to enter the house of Sayyida Hafsa (may Allah be pleased with her). Aisha (may Allah be pleased with her) said: I said, "O Messenger of Allah! This man is asking for permission (to enter)?" So the Messenger of Allah (peace and blessings be upon him) said: "I think he is such-and-such a man, Hafsa's foster-uncle." Then Aisha (may Allah be pleased with her) said: "O Messenger of Allah! If such-and-such a man, who was her foster-uncle, were alive, could he come to me (in my house)?" The Messenger of Allah (peace and blessings be upon him) said: "Yes, the relationships that are forbidden due to (real) lineage are also forbidden due to fosterage."

It is narrated from Urwah bin Zubair, may Allah have mercy on him, that the Badri Companion Abu Hudhaifah bin Utbah bin Rabi’ah had adopted (his slave) Salim, the freed slave of Abu Hudhaifah, may Allah be pleased with him, just as the Messenger of Allah, peace and blessings be upon him, had adopted Zaid bin Harithah, may Allah be pleased with him. Abu Hudhaifah married Salim to his niece Fatimah bint Walid bin Utbah bin Rabi’ah, who was among the first women to migrate and was one of the most virtuous women of the Quraysh in her time, because he considered him his son. When Allah Almighty revealed in His Book (the Noble Qur’an) regarding our master Zaid bin Harithah, may Allah be pleased with him: Call them by (the names of) their fathers; that is more just in the sight of your Lord. If you do not know their fathers, then they are your brothers in religion and your freed slaves. [ الاحزاب: 5 ] Everyone returned his adopted son to his (real) father, and if his father was not known, then he was attributed to the freed slaves. Then Abu Hudhaifah’s wife, Sahla bint Suhail, came to the Messenger of Allah, peace and blessings be upon him; she was from Banu Amir bin Lu’ayy. She said: O Messenger of Allah! We used to consider Salim as a son, while I am sometimes in my work clothes or in a single garment, and we live in the same house. What do you think about this? We have heard that the Messenger of Allah, peace and blessings be upon him, said:“Breastfeed him five times, and he will become unlawful (mahram) to you because of that milk.”(He will become a foster son.) She considered him her foster son. Umm al-Mu’minin, Lady Aisha, may Allah be pleased with her, adopted this practice. If she wanted to allow a man to enter upon her, she would order her sister Umm Kulthum bint Abi Bakr al-Siddiq, may Allah be pleased with him, and her nieces to breastfeed him. All the wives of the Prophet, peace and blessings be upon him, refused to allow people to enter upon them through breastfeeding and said: No, by Allah! We think that the permission for Sahla bint Suhail to make Salim her foster son was a special concession for her. By Allah! No man will ever enter upon us through this breastfeeding. This was the opinion of the wives of the Prophet, peace and blessings be upon him, regarding the breastfeeding of an adult man. Abu al-Hasan (the narrator) said: This hadith becomes elevated and connected (marfu’ muttasil) because of Urwah’s statement that (Aisha, may Allah be pleased with her, adopted this practice).
