‘Amr b. Shu’aib, on his father’s authority, said that his grandfather reported God’s Messenger as saying, “If any man marries a woman and cohabits with her it is not lawful for him to marry her daughter, but if he does not cohabit with her he may marry her daughter; and if any man marries a woman it is not lawful of him to marry her mother whether he has cohabited with her or not.” Tirmidhi transmitted it, saying this is a tradition which is not sound, with respect to its isnad. It is transmitted only by Ibn Lahi'a and al-Muthanna b. as-Sabbah on the authority of ‘Amr b. Shu’aib, and they are both declared to be weak in tradition.

“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 told of a man who went to God's Messenger and said, “I have a slave-girl who is our servant and I have intercourse with her, but do not want her to conceive.” He replied, “Withdraw your penis from her if you wish, for what is decreed for her will come to her.” After a time the man came and told him the girl had become pregnant, and he said, “I told you that what was decreed for her would come to her.” Muslim transmitted it.

We went out with God’s Messenger on the expedition to the B. al-Mustaliq (an expedition in 6 A.H) and took some Arab women captive, and we desired the women, for we were suffering from the absence of our wives. We liked withdrawing the penis and wanted to do so, but we asked ourselves whether we could do it when God’s Messenger was among us before asking him. So we asked him about that and he replied, “It does not matter if you do not do it, for every soul that is to be born up to the day of resurrection will be born.” (Bukhari and Muslim.)

He said that when God’s Messenger was asked about withdrawing the penis he replied, “The child does not come from all the liquid, and when God intends to create anything nothing can prevent Him.” Muslim transmitted it.

Sa'd b. Abu Waqqas told of a man who came to God's Messenger and said that he withdrew his penis from his wife. He asked him why he did that and the man replied that he feared for her child, so God’s Messenger said, “If that were injurious it would injure the Persians and the Greeks.”** This is explained as referring to a woman who is suckling a child, and the fear that the child, would be injured if she became pregnant.Muslim transmitted it.

I was with God’s Messenger along with some people when he was saying, “I intended to prohibit suckling during pregnancy* but I considered the Greeks and the Persians and saw that they suckled their children during pregnancy without any injury being caused to their children thereby.” Then they asked him about withdrawing the penis and God’s Messenger replied, “That is the secret burying alive” and reference is made to it in the words, “When the girl buried alive will be asked (Al-Qur’an 81:8).”*(Ghila. It means either suckling during pregnancy, or intercourse with a woman while she is suckling a child. Muslim transmitted it.

Abu Sa'id al-Khudri reported God's Messenger as saying, “The most serious breach of trust in God’s sight on the day of resurrection ...” A version has, “Among those who will have the worst position in God’s sight on the day of resurrection is the man who has intercourse with his wife, and she with him, and then spreads her secret.”** i.e. talks about the subject to others, or tells people about defects or beauties he has found in her.Muslim transmitted it.

God’s Messenger received the revelation, “Your wives are a tilth to you, so come to your tilth . . .” (Al-Qur’an 2:223) that means from in front or behind, but avoid the anus and intercourse during menstruation. Tirmidhi and Ibn Majah transmitted it.

Khuzaima b. Thabit reported the Prophet as saying, “God is not ashamed of the truth. Do not have intercourse with women through the anus.”Ahmad, Tirmidhi, Ibn Majah and Darimi transmitted it.

Abu Huraira reported God’s Messenger as saying, “He who has intercourse with his wife through her anus is accursed.” Ahmad and Abu Dawud transmitted 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.

Asma’ daughter of Yazid said she heard God’s Messenger say, “Do not kill your children secretly, for the milk with which a child is suckled while his mother is pregnant overtakes the horseman and throws him from his horse.”* * It is here said that a child which is suckled while his mother is pregnant will suffer from it in later life, the tradition speaking specifically of his being thrown from his horse and killed.Abu Dawud transmitted it.

‘Umar b. al-Khattab said God’s Messenger forbade withdrawing the penis from a free woman unless she gives permission. Ibn Majah transmitted it.

'Urwa told on' A’isha’s authority that God’s Messenger said to her concerning Barira, “Take her and set her free.” Now her husband was a slave, so God’s Messenger gave her her choice and she chose to separate from him; but if he had been free he would not have given her her choice. (Bukhari and Muslim.)

Barira’s husband was a negro slave called Mughith whom I can still picture going round behind her in the streets of Medina weeping with the tears flowing on his beard. The Prophet said to al- ‘Abbas, “Are you not astonished, ‘Abbas, at Mughith’s love; of Barira and Barira’s hatred of Mughith?" The Prophet expressed a wish that she would take him back, but when she asked whether he was giving her a command and he replied that he was merely interceding, she said, “I have no need of him.” Bukhari 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.

She said that Barira became free when she was with Mughith and God’s Messenger gave her her choice saying, “If he has intercourse with you, you will not be allowed to exercise choice.”Abu Dawud transmitted it.
