The Messenger of Allah (ﷺ) came to me and I said to him: Have you any inclination towards my the daughter of Abu Sufyan? 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.

One suckling or two do not make (marriage) unlawful.

A bedouin came to Allah's Apostle (ﷺ) 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 (ﷺ) said: One suckling or two do not make the (marriage) unlawful.

Allah's Apostle, does one suckling make the (marriage) unlawful? He said: No.

Being suckled once or twice, or one suckling or two, do not make marriage unlawful.

'A'isha (Allah be pleased with, her) reported that it had been revealed in the Holy Qur'an that ten clear sucklings make the marriage unlawful, then it was abrogated (and substituted) by five sucklings and Allah's Apostle (ﷺ) died and it was before that time (found) in the Holy Qur'an (and recited by the Muslims).

There was revealed in the Holy Qur'an ten clear sucklings, and then five clear (sucklings).

Messengerof Allah, I see on the face of Abu Hudhaifa (signs of disgust) on entering of Salim (who is an ally) into (our house), whereupon Allah's Apostle (ﷺ) said: Suckle him. She said: How can I suckle him as he is a grown-up man? Allah's Messenger (ﷺ) smiled and said: I already know that he is a young man 'Amr has made this addition in his narration that he participated in the Battle of Badr and in the narration of Ibn 'Umar (the words are): Allah's Messenger (ﷺ) laughed.

A young boy who is at the threshold of puberty comes to you. I, however, do not like that he should come to me, whereupon 'A'isha (Allah be pleased with her) said: Don't you see in Allah's Messenger (ﷺ) a model for you? She also said: The wife of Abu Hudhaifa said: Messenger of Allah, Salim comes to me and now he is a (grown-up) person, and there is something that (rankles) in the mind of Abu Hudhaifa about him, whereupon Allah's Messenger (ﷺ) said: Suckle him (so that he may become your foster-child), and thus he may be able to come to you (freely).

Allah's Messenger (ﷺ) visited me when a man was sitting near me, and he seemed to disapprove of that. And I saw signs of anger on his face and I said: Messenger of Allah, he is my brother by forsterage, whereupon he said: Consider who your brothers are because of fosterage since fosterage is through hunger (i. e. in infancy).

Likewise, the above hadith has been narrated through another chain.

Sa'd b. Abu Waqqas and Abd b. Zam'a (Allah be pleased with them) disputed with each other over a young boy. Sa'd said: Messenger of Allah, he is the son of my brother 'Utba b. Abu Waqqas as he made it explicit that he was his son. Look at his resemblance. Abd b. Zam'a said Messenger of Allah, he is my brother as he was born on the bed of my father from his slave-girl. Allah's Messenger (ﷺ) looked at his resemblance and found a clear resemblance with 'Utba. (But) he said: "He is yours O 'Abd (b. Zam'a), for the child is to be attributed to one on whose bed it is born, and stoning for a fornicator. Sauda bint Zam'a, O you should observe veil from him." So he did not see Sauda at all. Muhammad b. Rumh did not make a mention (of the words): "O Abd."

One day Allah's Apostle (ﷺ) visited me looking pleased and he said: 'A'isha, don't you see Mujazziz al-Mudliji? (He) entered (my house) and saw Usama and Zaid with a rug over them covering their heads, but their feet appeared, and (he) said: These feet are related to one another.

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.

A hadith like this is narrated on the authority of Hammam, Sa'id, Bishr b 'Umar, but with a small variation of words.

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

Messenger of Allah, marry my sister 'Azza, whereupon Allah's Messenger (ﷺ) 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 (ﷺ) said: That is not lawful for me. I said: Messenger of Allah, we discussed that You intend to marry Durrah bint Abu Salama. He (the Holy Prophet) said: You mean the daughter of Abu Salama? 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.

By Allah, we do not find this but a sort of concession given by Allah's Messenger (ﷺ) only for Salim, and no one was ging to be allowed to enter (our houses) with this type of fosterage and we do not subscribe to this view.

This hadith is narrated on the authority of Abu al-Ahwas with another chain of transmitters and a slight variation of words.

Except what your right hands possess out of them are lawful for you; and he did not mention" when their 'idda period comes to an end".
