Narrated `Amra bint `Abdur-Rahman: `Aisha, the wife of the Prophet told her that once Allah's Apostle was with her and she heard somebody asking permission to enter Hafsa's house. She said, "O Allah's Apostle! This man is asking permission to enter your house." Allah's Apostle replied, "I think he is so-and-so (meaning the foster uncle of Hafsa). What is rendered illegal because of blood relations, is also rendered illegal because of the corresponding foster-relations."

Narrated Aisha: Aflah asked the permission to visit me but I did not allow him. He said, "Do you veil yourself before me although I am your uncle?" `Aisha said, "How is that?" Aflah replied, "You were suckled by my brother's wife with my brother's milk." I asked Allah's Apostle about it, and he said, "Aflah is right, so permit him to visit you."

Narrated Ibn `Abbas: The Prophet said about Hamza's daughter, "I am not legally permitted to marry her, as foster relations are treated like blood relations (in marital affairs). She is the daughter of my foster brother."

Narrated `Amra bint `Abdur-Rahman: That `Aisha the wife of the Prophet told her uncle that once, while the Prophet was in her house, she heard a man asking Hafsa's permission to enter her house. `Aisha said, "I said, 'O Allah's Apostle! I think the man is Hafsa's foster uncle.' " `Aisha added, "O Allah's Apostle! There is a man asking the permission to enter your house." Allah's Apostle replied, "I think the man is Hafsa's foster uncle." `Aisha said, "If so-and-so were living (i.e. her foster uncle) would he be allowed to visit me?" Allah's Apostle said, "Yes, he would, as the foster relations are treated like blood relations (in marital affairs).

Narrated `Aisha: Aflah, the brother of Abi Al-Quais, asked permission to visit me after the order of Al-Hijab was revealed. I said, "I will not permit him unless I take permission of the Prophet about him for it was not the brother of Abi Al-Qu'ais but the wife of Abi Al-Qu'ais that nursed me." The Prophet entered upon me, and I said to him, "O Allah's Messenger! Allah, the brother of Abi Al-Qu'ais asked permission to visit me but I refused to permit him unless I took your permission." The Prophet said, "What stopped you from permitting him? He is your uncle." I said, "O Allah's Messenger! The man was not the person who had nursed me, but the woman, the wife of Abi Al-Qu'ais had nursed me." He said, "Admit him, for he is your uncle. Taribat Yaminuki (may your right hand be saved)" `Urwa, the sub-narrator added: For that `Aisha used to say, "Consider those things which are illegal because of blood relations as illegal because of the corresponding foster relations."

Narrated `Aisha: (the wife of the Prophet) that while Allah's Apostle was with her, she heard a voice of a man asking permission to enter the house of Hafsa. `Aisha added: I said, "O Allah's Apostle! This man is asking permission to enter your house." The Prophet said, "I think he is so-and-so," naming the foster-uncle of Hafsa. `Aisha said, "If so-and-so," naming her foster uncle, "were living, could he enter upon me?" The Prophet said, "Yes, for foster suckling relations make all those things unlawful which are unlawful through corresponding birth (blood) relations."

Narrated Ibn `Abbas: It was said to the Prophet, "Won't you marry the daughter of Hamza?" He said, "She is my foster niece (brother's daughter). "

Narrated Um Habiba: (daughter of Abu Sufyan) I said, "O Allah's Apostle! Marry my sister. the daughter of Abu Sufyan." The Prophet said, "Do you like that?" I replied, "Yes, for even now I am not your only wife and I like that my sister should share the good with me." The Prophet said, "But that is not lawful for me." I said, We have heard that you want to marry the daughter of Abu Salama." He said, "(You mean) the daughter of Um Salama?" I said, "Yes." He said, "Even if she were not my step-daughter, she would be unlawful for me to marry as she is my foster niece. I and Abu Salama were suckled by Thuwaiba. So you should not present to me your daughters or your sisters (in marriage)." Narrated 'Urwa:Thuwaiba was the freed slave girl of Abu Lahb whom he had manumitted, and then she suckled the Prophet. When Abu Lahb died, one of his relatives saw him in a dream in a very bad state and asked him, "What have you encountered?" Abu Lahb said, "I have not found any rest since I left you, except that I have been given water to drink in this (the space between his thumb and other fingers) and that is because of my manumitting Thuwaiba."

Narrated Aisha: that Aflah the brother of Abu Al-Qu'ais, her foster uncle, came, asking permission to enter upon her after the Verse of Al-Hijab (the use of veils by women) was revealed. `Aisha added: I did not allow him to enter, but when Allah's Apostle came, I told him what I had done, and he ordered me to give him permission.

Narrated Um Habiba: I said, "O Allah's Apostle! Do you like to have (my sister) the daughter of Abu Sufyan?" The Prophet said, "What shall I do (with her)?" I said, "Marry her." He said, "Do you like that?" I said, "(Yes), for even now I am not your only wife, so I like that my sister should share you with me." He said, "She is not lawful for me (to marry)." I said, "We have heard that you want to marry." He said, "The daughter of Um Salama?" I said, "Yes." He said, "Even if she were not my stepdaughter, she should be unlawful for me to marry, for Thuwaiba suckled me and her father (Abu Salama). So you should neither present your daughters, nor your sisters, to me."

Narrated Um Habiba: I said, "O Allah's Apostle! Marry my sister, the daughter of Abu Sufyan." He said, "Do you like that?" I said, "Yes, for even now I am not your only wife; and the most beloved person to share the good with me is my sister." The Prophet said, "But that is not lawful for me (i.e., to be married to two sisters at a time.)" I said, "O Allah's Apostle! By Allah, we have heard that you want to marry Durra, the daughter of Abu Salama." He said, "You mean the daughter of Um Salama?" I said, "Yes." He said, "By Allah! Even if she were not my stepdaughter, she would not be lawful for me to marry, for she is my foster niece, for Thuwaiba has suckled me and Abu Salama; so you should neither present your daughters, nor your sisters to me."

Ibn `Abbas said: "Hint your intention of marrying' is made by saying (to the widow) for example: "I want to marry, and I wish that Allah will make a righteous lady available for me.' " Al-Qasim said: One may say to the widow: 'I hold all respect for you, and I am interested in you; Allah will bring you much good, or something similar 'Ata said: One should hint his intention, and should not declare it openly. One may say: 'I have some need. Have good tidings. Praise be to Allah; you are fit to remarry.' She (the widow) may say in reply: I am listening to what you say,' but she should not make a promise. Her guardian should not make a promise (to somebody to get her married to him) without her knowledge. But if, while still in the Iddat period, she makes a promise to marry somebody, and he ultimately marries her, they are not to be separated by divorce (i.e., the marriage is valid).

Narrated `Aisha: My foster uncle came and asked permission (to enter) but I refused to admit him till I asked Allah's Apostle about that. He said, "He is your uncle, so allow him to come in." I said, "O Allah's Apostle! I have been suckled by a woman and not by a man." Allah's Apostle said, "He is your uncle, so let him enter upon you." And that happened after the order of Al-Hijab (compulsory veiling) was revealed. All things which become unlawful because of blood relations are unlawful because of the corresponding foster suckling relations.

Narrated Um Habiba: (the wife of the Prophet) I said, "O Allah's Apostle! Will you marry my sister, the daughter of Abu Sufyan." The Prophet said, "Do you like that?" I said, "Yes, for I am not your only wife, and the person I like most to share the good with me, is my sister." He said, "That is not lawful for me." I said, "O Allah's Apostle! We have heard that you want to marry Durra, the daughter of Abu Salama." He said, "You mean the daughter of Um Salama?" I said, "Yes." He said, "Even if she were not my stepdaughter, she is unlawful for me, for she is my foster niece. Thuwaiba suckled me and Abu Salama. So you should not present to me your daughters and sisters." Narrated 'Urwa: Thuwaiba had been a slave girl whom Abu Lahab had emancipated.

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 Apostle entered upon me, and I said, "O Allah's Apostle! 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)
