Narrated Abdullah Ibn Abbas: Ibn Umar misunderstood (the Quranic verse, "So come to your tilth however you will")--may Allah forgive him. The fact is that this clan of the Ansar, who were idolaters, lived in the company of the Jews who were the people of the Book. They (the Ansar) accepted their superiority over themselves in respect of knowledge, and they followed most of their actions. The people of the Book (i. e. the Jews) used to have intercourse with their women on one side alone (i. e. lying on their backs). This was the most concealing position for (the vagina of) the women. This clan of the Ansar adopted this practice from them. But this tribe of the Quraysh used to uncover their women completely, and seek pleasure with them from in front and behind and laying them on their backs. When the muhajirun (the immigrants) came to Madina, a man married a woman of the Ansar. He began to do the same kind of action with her, but she disliked it, and said to him: We were approached on one side (i. e. lying on the back); do it so, otherwise keep away from me. This matter of theirs spread widely, and it reached the Messenger of Allah ﷺ. So Allah, the Exalted, sent down the Quranic verse: "Your wives are a tilth to you, so come to your tilth however you will, " i. e. from in front, from behind or lying on the back. But this verse meant the place of the delivery of the child, i. e. the vagina.

Bahz bin Hakim reported on the authority of his father from his grandfather (Muawiyah ibn Haydah) as saying: I said: Messenger of Allah, how should we approach our wives and how should we leave them? He replied: Approach your tilth when or how you will, give her (your wife) food when you take food, clothe when you clothe yourself, do not revile her face, and do not beat her. Abu Dawud said: The version of Shubah has: That you give her food when you have food yourself, and that you clothe her when you clothe yourself.

Narrated Abu Hurairah: The Prophet ﷺ said: He who has intercourse with his wife through her anus is accursed.

Muhammad bin Al Munkadir said I heard Jabir say The Jews used to say “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. ”
