Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) was with her and she heard the voice of a person seeking permission to enter the house of Hafsa رضی اللہ عنہا. 'A'isha (رضی اللہ عنہا) said: Allah's Messenger, he is the person who seeks permission to enter your house, whereupon Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) said: I think he is so and so (uncle of Hafsa رضی اللہ عنہا by reason of fosterage). 'A'isha رضی اللہ عنہا said: Messenger of Allah, if so and so (her uncle by reason of fosterage) were alive, could he enter my house? Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) said: Yes. Fosterage makes unlawful what consanguinity makes unlawful.

Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) as saying: What becomes unlawful through breastfeeding is that which becomes unlawful through birth.

Abdullah bin Abi Bakr narrated a Hadith similar to that of Hisham bin Urwah (no. 3569), with this chain.

Aflah, the brother of Abu'l-Qu'ais, who was her uncle by reason of fosterage, came, and asked her permission (to enter the house) after seclusion (Hijab) was instituted. I refused to admit him. When Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) came, I informed him what I had done. He commanded me to grant him permission (as the brother of her foster-father was also her uncle).

There came to me Aflah bin Abu Qulais, my uncle by reason of fosterage; the rest of the hadith is the same (but with this) addition: I ('A'isha رضی اللہ عنہا) said (to the Holy Prophet ﷺ): It was the woman who suckled me and not the man, whereupon he (Allah's Messenger ﷺ) said: May your hands or your right hand be besmeared with dust (you were mistaken).

There came Aflah the brother, of Abu'l-Qu'ais, who sought her permission (to enter) after seclusion was instituted, and AbuQu'ais was the father of 'A'isha by reason of fosterage. 'A'isha رضی اللہ عنہا said: By Allah, I would not permit Aflah unless I have solicited the opinion of Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) for Abu Qulais has not suckled me, but his wife has given me suck. 'A'isha' ( رضی اللہ عنہا) said: When Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) entered, I said: Allah's Messenger, Aflah is the brother of Abu'l-Qulais; he came to me to seek my permission for entering (the houst). I did not like the idea of granting him permission until I had solicited your opinion. Thereupon Allah's Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) said: Grant him permission. 'Urwa said it was on account of this that 'A'isha رضی اللہ عنہا used to say. What is unlawful by reason of consanguinity is unlawful by reason of fosterage.

There came Aflah, the brother of Abu'l Qulais (Allah be pleased with him), and sought permission from her, the rest of the hadith is the same (except for the words that the Holy Prophet) said: He is your uncle. Let your hand be besmeared with dust. Abu'l Qulais was the husband of the woman who had suckled 'A'isha (رضی اللہ عنہا).

My foster uncle came to me and sought permission (to enter the house), but I refused him permission until I had solicited the opinion of Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ). When Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) came, I said to him: My foster-uncle sought my permission to (enter the house), but I did not permit him, whereupon Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) said: You better admit your uncle (into the house). I ('A'isha) said: It was the woman who suckled me and not the man. (But he) said: He is your uncle, admit him.

The brother of Abu'l-Qu'ais sought permission from her ('A'isha رضی اللہ عنہا ) (to enter the house). The rest is the same.

"Abu Al-Quais asked from permission to enter upon her.

My foster-uncle Abu'l Ja'd (kunya of Aflah) sought permission from me, which I refused. (Hisham said to me that Abu'l-Ja'd was in fact Abu'l-Qu'ais). When Allah's Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) came, I ('A'isha) informed him about it. He said: Why did you not permit him? Let your right hand or hand be besmeared with dust.

Her foster-uncle whose name was Aflah sought permission from her (to enter the house) but she observed seclusion from him, and informed Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) who said to her: Don't observe veil from him for he is Mahram (one with whom marriage cannot be contracted) on account of fosterage as one is Mahram on account of consanguinity.

Aflah bin Qu'ais sought permission from me (to enter the house), but I refused to grant him the permission, and he sent me (the message saying): I am your uncle (in the sense) that the wife of my brother has suckled you, (but still) I refused to grant him permission. There came the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) and I made a mention of it to him, and he said: He can enter (your house), for he is your uncle.

Messenger of Allah, why is it that you select (your wife) from among the Quraish, but you ignore us (the nearest of the kin)? Thereupon he said: Have you anything for me (a suitable match for me)? I said; Yes, the daughter of Hamza رضی اللہ عنہ , whereupon Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) said: She is not lawful for me, for she is the daughter of my brother by reason of fosterage.

A hadith like this has been narrated on the authority of A'mash with the same chain of transmitters.

It was proposed that he (the Holy Prophet ﷺ) be married to the daughter of Hamza رضی اللہ عنہ , whereupon he said: She is not lawful for me for she is the daughter of my foster-brother, and that is unlawful by reason of fosterage what is unlawful by reason of genealogy.

The daughter of my brother through the breastfeeding." In the Hadith of Saeed it says: "Verily what become unlawful through breastfeeding is that which becomes unlawful through blood ties. "And in the hadith of Bishr bin Umar (instead of the hadith from Jabir bin Zayd), it is: "I heard from Jabir bin Zayd."

It was said to the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌): Is not the daughter of Hamza رضی اللہ عنہ a suitable match for you? Or it was said: Why don't you propose to marry the daughter of Hamza, the son of Abdul-Muttalib رضی اللہ عنہ? Thereupon he said: Hamza رضی اللہ عنہ is my brother by reason of fosterage.

The Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) came to me and I said to him: Have you any inclination towards my the daughter of Abu Sufyan رضی اللہ عنہ ? He (the Holy Prophet) said: Then what should I do? I said: Marry her. He said: Do you like that? I said: I am not the exclusive (wife) of yours; I, therefore, wish to join my sister in good. He, said: She is not lawful for me. I said: I have been informed that you have given the proposal of marriage to Durrah daughter of Abu Salama He raid: You mean the daughter of Umm Salama? I said: Yes. He said: Even if she had not been my step-daughter brought up under my guardianship, she would not have been lawful for me, for she is the daughter of my foster-brother (Hamza), for Thuwaiba had suckled me and her father. So do not give me the proposal of the marriage of your daughters and sisters.

This hadith has been narrated on the authority of Hisham with the same chain of transmitters.

She said to Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌): Messenger of Allah, marry my sister 'Azza, whereupon Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) said: Do you like it? She said: Yes, Messenger of Allah, I am not the exclusive wife of yours, and I wish that the person who joins me in good should be my sister. Thereupon Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) said: That is not lawful for me. I said: Messenger of Allah, we discussed that You intend to marry Durrah bint Abu Salama رضی اللہ عنہا. He (the Holy Prophet) said: You mean the daughter of Abu Salama رضی اللہ عنہا? She said: Yes, whereupon Allah's Messenger (may. peace be upon him) said: Even if she were not the step-daughter of mine, brought up under my guardianship, she would not have been lawful for me, for she is the daughter of my foster-brother. Thuwaiba gave me suck and to Abu Salama (also), so do not offer to me your daughters and sisters.

The above hadith is narratted through other chains except they did not mention 'Azza like the chain of Yazid Bin Abi Habib.

Suwaid and Zubair reported Allah's Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) as saying: One suckling or two do not make (marriage) unlawful.

A Bedouin came to Allah's Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) when he was in my house and said: Allah's Apostle, I have had a wife and I married another besides her, and my first wife claimed that she had suckled once or twice my newly married wife, thereupon Allah's Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) said: One suckling or two do not make the (marriage) unlawful.

A person from Banu 'Amir bin Sa'sa said: Allah's Apostle, does one suckling make the (marriage) unlawful? He said: No
