‘Ali said, “Messenger of God, would you like the daughter of your paternal uncle Hamza, for she is the most beautiful girl in Quraish?” He replied, “Do you not know that Hamza is my foster-brother, and that God has prohibited by reason of fosterage what He has prohibited by reason of genealogy?” Muslim transmitted it.

She said that the Prophet visited her when a man was with her and he seemed to disapprove of that. She told him that he was her brother and he replied, “Consider* who your brothers are, for fosterage is that consequent on hunger” (Fosterage applies only to infants and not to children who are able to take solid food).* The verb is in the plural, indicating that this is a general instruction and not simply a reply to A’isha.(Bukhari and Muslim.)

Abu Huraira said that God’s Messenger forbade that a woman should be married to one who had married her paternal aunt, or a paternal aunt to one who had married her brother’s daughter, or a woman to one who had married her maternal aunt, or a maternal aunt to one who had married her sister's daughter. A younger sister must not be married to one who has married an elder sister, nor an elder sister to one who has married a younger sister. Tirmidhi, Abu Dawud, Darimi and Nasa’i transmitted it, Nasa’i’s version ending with “her sister’s daughter.”

My maternal uncle Abu Burda b. Niyar passed me carrying a standard, and I asked him where he was going. He replied, “The Prophet has sent me to bring him the head of a man who has married his father’s wife.” A version by Abu Dawud, Nasa’i, Ibn Majah and Darimi has, “He has ordered me to cut off his head and take his property.” This version has “my paternal uncle” instead of “my maternal uncle.”Tirmidhi and Abu Dawud transmitted it.

When I was sitting with the Prophet a woman came forward and the Prophet spread out his cloak and she sat on it. Then when she went away someone said that this woman had suckled the Prophet. Abu Dawud transmitted it.

Ibn ‘Abbas told that a woman who had accepted Islam married, and her husband (i.e. the one she had left to marry another when she became a Muslim) went to the Prophet and said, "Messenger of God, I have accepted Islam and she knew that I had done so.” So God’s Messenger took her away from her second husband and restored her to her first. In a version he said, “She accepted Islam along with me,” so he restored her to him. Abu Dawud transmitted it.

Seven classes of women are prohibited by reason of consanguinity and seven by reason of relationship by marriage. He then recited, "Prohibited to you are your mothers ...” (Al-Qur’an 4:23).Bukhari transmitted it.

“When a man has intercourse with his wife through the vagina, but being on her back, the child will have a squint,” so the verse came down, “Your wives are a tilth to you, so come to your tilth however you will” (Al-Qur’an 2:223).(Bukhari and Muslim.)

He said that in the period when the Qur'an was coming down they used to withdraw the penis.* * i.e. before emission of semen, to avoid conception.(Bukhari and Muslim.) Muslim added that the Prophet heard of that and did not prohibit it.

He reported God’s Messenger as saying, “God will not look at him who has intercourse with his wife through her anus.” It is transmitted in Sharh as-sunna.

Ibn ‘Abbas reported God’s Messenger as saying, “God will not look at a man who has intercourse with a man or a woman through the anus.” Tirmidhi transmitted it.

‘A’isha said she wanted to set free two slaves of hers who were married, so she consulted the Prophet and he ordered her to begin with the man before the woman. Abu Dawud and Nasa’i transmitted it.

Abu Salama said he asked ‘A’isha how much the Prophet had given as dower, and she replied that his dower to his wives was twelve uqiyas* and a nashsh. She asked whether he knew what a nashsh was, and when he replied that he did not, she said it was half an uqiya; so the total was five hundred dirhams. * The uqiya was 40 dirhams.Muslim transmitted it. Nashsh is in the nominative in Sharh as-sunna and all the sources.

Jabir reported God’s Messenger as saying, "If anyone gives as a dower to his wife two handfuls of flour or dates he has made her lawful for him.” Abu Dawud transmitted it.

He said that God's Messenger did not hold such a wedding-feast for any of his wives as he did for Zainab. He held a wedding-feast with a sheep. (Bukhari and Muslim.)

He said that God’s Messenger held a wedding-feast when he took up cohabitation with Zainab daughter of Jahsh and gave the people their fill of bread and meat. Bukhari transmitted it.

The Prophet stayed three nights between Khaibar and Medina when he took up cohabitation with Safiya, and I called the Muslims to his wedding-feast which included no bread or meat. He just ordered some cloths to be spread, and dates, dried curd and clarified butter were thrown on them. Bukhari transmitted it.

Safiya daughter of Shaiba said the Prophet held a wedding-feast for one of his wives with two muds of barley. Bukhari transmitted it.

‘Ikrima, on the authority of Ibn ‘Abbas, said the Prophet forbade that the food of two people who were rivalling one another should be eaten. Abu Dawud transmitted it. Muhyi as-Sunna said the sound version is that it comes from ‘Ikrima from the Prophet in mursal form.

Abu Huraira reported the Prophet as saying, “When one of you visits his brother Muslim he should eat of his food without asking questions and drink from what he provides without asking questions.” Baihaqi transmitted the three traditions in Shu'ab al-iman, saying that if [the last one] is sound, it is because a Muslim would obviously give him only food and drink which were lawful in his opinion.
