Sahih al-Bukhari

"Forbidden for you (for marriages) are your mothers..." (4:23). 'Abdullah bin Ja'far married the daughter and wife of 'Ali at the same time (they were step-daughter and mother). Ibn Sirin said, "There is no harm in that." But Al-Hasan Al-Basri disapproved of it at first, but then said that there was no harm in it. Al-Hasan bin Al-Hasan bin 'Ali married two of his cousins in one night. Ja'far bin Zaid disapproved of that because of it would bring hatred (between the two cousins), but it is not unlawful, as Allah said, "Lawful to you are all others . (4:24). Ibn 'Abbas said: "If somebody commits illegal sexual intercourse with his wife's sister, his wife does not become unlawful for him." And narrated Abu Ja'far, "If a person commits homosexuality with a boy, then the mother of that boy is unlawful for him to marry." Narrated Ibn 'Abbas, "If one commits illegal sexual intercourse with his mother in law, then his married relation to his wife does not become unlawful." Abu Nasr reported to have said that Ibn 'Abbas in the above case, regarded his marital relation to his wife unlawful, but Abu Nasr is not known well for hearing Hadith from Ibn 'Abbas. Imran bin Hussain, Jabir b. Zaid, Al-Hasan and some other Iraqi's, are reported to have judged that his marital relations to his wife would be unlawful. In the above case Abu Hurairah said, "The marital relation to one's wife does not become unlawful except if one as had sexual intercourse (with her mother)." Ibn Al-Musaiyab, 'Urwa, and Az-Zuhri allows such person to keep his wife. 'Ali said, "His marital relations to his wife does not become unlawful."

I said, "O Allah's Messenger (ﷺ)! Do you like to have (my sister) the daughter of Abu Sufyan?" The Prophet (ﷺ) 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."

I said, "O Allah's Messenger (ﷺ)! 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 (ﷺ) said, "But that is not lawful for me (i.e., to be married to two sisters at a time.)" I said, "O Allah's Messenger (ﷺ)! 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."

Allah's Messenger (ﷺ) forbade that a woman should be married to man along with her paternal or maternal aunt.

Allah's Messenger (ﷺ) said, "A woman and her paternal aunt should not be married to the same man; and similarly, a woman and her maternal aunt should not be married to the same man."

The Prophet (ﷺ) forbade that a woman should be married to a man along with her paternal aunt or with her maternal aunt (at the same time). Az-Zuhri (the sub-narrator) said: There is a similar order for the paternal aunt of the father of one's wife, for 'Urwa told me that `Aisha said, "What is unlawful because of blood relations, is also unlawful because of the corresponding foster suckling relations."

Allah's Messenger (ﷺ) forbade Ash-Shighar, which means that somebody marries his daughter to somebody else, and the latter marries his daughter to the former without paying Mahr.

Khaula bint Hakim was one of those ladies who presented themselves to the Prophet (ﷺ) for marriage. `Aisha said, "Doesn't a lady feel ashamed for presenting herself to a man?" But when the Verse: "(O Muhammad) You may postpone (the turn of) any of them (your wives) that you please,' (33.51) was revealed, " `Aisha said, 'O Allah's Messenger (ﷺ)! I do not see, but, that your Lord hurries in pleasing you.' "

The Prophet (ﷺ) got married while he was in the state of Ihram.

I said to Ibn `Abbas, "During the battle of Khaibar the Prophet (ﷺ) forbade (Nikah) Al-Mut'a and the eating of donkey's meat."

I heard Ibn `Abbas (giving a verdict) when he was asked about the Mut'a with the women, and he permitted it (Nikah-al-Mut'a). On that a freed slave of his said to him, "That is only when it is very badly needed and women are scarce." On that, Ibn `Abbas said, "Yes."

While we were in an army, Allah's Messenger (ﷺ) came to us and said, "You have been allowed to do the Mut'a (marriage), so do it."

Allah's Messenger (ﷺ)'s said, "If a man and a woman agree (to marry temporarily), their marriage should last for three nights, and if they like to continue, they can do so; and if they want to separate, they can do so." I do not know whether that was only for us or for all the people in general. Abu `Abdullah (Al-Bukhari) said: `Ali made it clear that the Prophet said, "The Mut'a marriage has been cancelled (made unlawful).

I was with Anas while his daughter was present with him. Anas said, "A woman came to Allah's Apostle and presented herself to him, saying, 'O Allah's Messenger (ﷺ), have you any need for me (i.e. would you like to marry me)?' "Thereupon Anas's daughter said, "What a shameless lady she was ! Shame! Shame!" Anas said, "She was better than you; she had a liking for the Prophet (ﷺ) so she presented herself for marriage to him."

A woman presented herself to the Prophet (for marriage). A man said to him, "O Allah's Messenger (ﷺ)! (If you are not in need of her) marry her to me." The Prophet (ﷺ) said, "What have you got?" The man said, "I have nothing." The Prophet (ﷺ) said (to him), "Go and search for something) even if it were an iron ring." The man went and returned saying, "No, I have not found anything, not even an iron ring; but this is my (Izar) waist sheet, and half of it is for her." He had no Rida' (upper garment). The Prophet (ﷺ) said, "What will she do with your waist sheet? If you wear it, she will have nothing over her; and if she wears it, you will have nothing over you." So the man sat down and when he had sat a long time, he got up (to leave). When the Prophet (ﷺ) saw him (leaving), he called him back, or the man was called (for him), and he said to the man, "How much of the Qur'an do you know (by heart)?" The man replied I know such Sura and such Sura (by heart)," naming the Suras The Prophet (ﷺ) said, "I have married her to you for what you know of the Qur'an ."

`Umar bin Al-Khattab said, "When Hafsa bint `Umar became a widow after the death of (her husband) Khunais bin Hudhafa As-Sahmi who had been one of the companions of the Prophet, and he died at Medina. I went to `Uthman bin `Affan and presented Hafsa (for marriage) to him. He said, "I will think it over.' I waited for a few days, then he met me and said, 'It seems that it is not possible for me to marry at present.' " `Umar further said, "I met Abu Bakr As-Siddique and said to him, 'If you wish, I will marry my daughter Hafsa to you." Abu Bakr kept quiet and did not say anything to me in reply. I became more angry with him than with `Uthman. I waited for a few days and then Allah's Messenger (ﷺ) asked for her hand, and I gave her in marriage to him. Afterwards I met Abu Bakr who said, 'Perhaps you became angry with me when you presented Hafsa to me and I did not give you a reply?' I said, 'Yes.' Abu Bakr said, 'Nothing stopped me to respond to your offer except that I knew that Allah's Apostle had mentioned her, and I never wanted to let out the secret of Allah's Messenger (ﷺ). And if Allah's Apostle had refused her, I would have accepted her.' "

Um Habiba said to Allah's Messenger (ﷺ) "We have heard that you want to marry Durra bint Abu-Salama." Allah's Messenger (ﷺ) said, "Can she be married along with Um Salama (her mother)? Even if I have not married Um Salama, she would not be lawful for me to marry, for her father is my foster brother."

"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).

Allah's Messenger (ﷺ) said (to me), "You were shown to me in a dream. An angel brought you to me, wrapped in a piece of silken cloth, and said to me, 'This is your wife.' I removed the piece of cloth from your face, and there you were. I said to myself. 'If it is from Allah, then it will surely be.' "

A woman came to Allah's Messenger (ﷺ) and said, "O Allah's Messenger (ﷺ)! I have come to you to present myself to you (for marriage)." Allah's Messenger (ﷺ) glanced at her. He looked at her carefully and fixed his glance on her and then lowered his head. When the lady saw that he did not say anything, she sat down. A man from his companions got up and said, "O Allah's Messenger (ﷺ)! If you are not in need of her, then marry her to me." The Prophet (ﷺ) said, "Have you got anything to offer." The man said, 'No, by Allah, O Allah's Messenger (ﷺ)!" The Prophet (ﷺ) said (to him), "Go to your family and try to find something." So the man went and returned, saying, "No, by Allah, O Allah's Messenger (ﷺ)! I have not found anything." The Prophet said, "Go again and look for something, even if it were an iron ring." He went and returned, saying, "No, by Allah, O Allah's Messenger (ﷺ)! I could not find even an iron ring, but this is my Izar (waist sheet).' He had no Rida (upper garment). He added, "I give half of it to her." Allah's Messenger (ﷺ) said "What will she do with your Izar? If you wear it, she will have nothing over herself thereof (will be naked); and if she wears it, then you will have nothing over yourself thereof ' So the man sat for a long period and then got up (to leave). When Allah's Messenger (ﷺ) saw him leaving, he ordered that he e called back. When he came, the Prophet (ﷺ) asked (him), "How much of the Qur'an do you know (by heart)?" The man replied, I know such Sura and such Sura and such Sura," naming the suras. The Prophet (ﷺ) said, "Can you recite it by heart?" He said, 'Yes." The Prophet (ﷺ) said, "Go I let you marry her for what you know of the Qur'an (as her Mahr).
