Sahih Muslim 1444a
'A'isha (Allah be pleased with her) reported tha Allah's Messenger (ﷺ) was with her and she heard the voice of a person seeking permission to enter the house of Hafsa. 'A'isha (Allah he pleased with her) said

Allah's Messenger, he is the person who seeks permission to enter your house, whereupon Allah's Messenger (ﷺ) said: I think he is so and so (uncle of Hafsa by reason of fosterage). 'A'isha said: Messenger of Allah, if so and so (her uncle by reason of fosterage) were alive, could he enter my house? Allah's Messenger (ﷺ) said: Yes. Fosterage makes unlawful what consanguinity makes unlawful.

Sahih Muslim 1444b
'A'isha (Allah be pleased with her) reported Allah's Messenger (ﷺ) as saying

"What becomes unlawful through breastfeeding is that which becomes unlawful through birth."

The above hadith is narrated through another chain.

Chapter 2: The prohibition that results from breastfeeding is related to the issue of the male

Sahih Muslim 1445a

'A'isha (Allah be pleased with her) reported that 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 (ﷺ) 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).

Sahih Muslim 1445b
'A'isha (Allah be pleased with her) reported

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

Sahih Muslim 1445c
'A'isha (Allah be pleased with her) reported that 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 said

By Allah, I would not permit Aflah unless I have solicited the opinion of Allah's Messenger (ﷺ) for Abu Qulais has not suckled me, but his wife has given me suck. 'A'isha' (Allah be pleased with her) said: When Allah's Messenger (ﷺ) 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 (ﷺ) said: Grant him permission. 'Urwa said it was on account of this that 'A'isha used to say. What is unlawful by reason of consanguinity is unlawful by reason of fosterage.

I ('A'isha) said: It was the woman who suckled me and not the man. (But he) said: He is your uncle, admit him.

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.
