Read all Ahadith in the book of suckling by sahih al muslim

A'isha (Allah be pleased with her) reported tha 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. '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 ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) 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 ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) said: Yes. Fosterage makes unlawful what consanguinity makes unlawful.

A'isha (Allah be pleased with her) reported Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) as saying: What becomes unlawful through breastfeeding is that which becomes unlawful through birth.

The above hadith is narrated through another chain.

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 ( ‌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).

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).

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 ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) 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 ( ‌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 used to say. What is unlawful by reason of consanguinity is unlawful by reason of fosterage.

This hadith has been narrated on the authority of Zuhri with the same chain of transmitters (that 'A'isha said): 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 (Allah be pleased with her).

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

This hadith has been narrated on the authority of Hisham with the same chain of transmitters (and the words are): The brother of Abu'l-Qu'ais sought permission from her ('A'isha) (to enter the house). The rest is the same.

This hadith has been narrated on the authority of Hisham with the same chain of transmitters but with a slight variation of words.
