Abu Sa'id al-Khudri · The Book of Marriage

The most wicked among the people in the eye of Allah on the Day of judgment is the men who goes to his wife and she comes to him, and then he divulges her secret.

We took women captives, and we wanted to do 'azl with them. We then asked Allah's Messen- ger (ﷺ) about it, and he said to us: Verily you do it, verily you do it, verily you do it, but the soul which has to be born until the Day of judg- ment must be born.

There is no harm if you do not do that, for it (the birth of the child) is something ordained. Muhammad (one of the narrators) said: (The words) La 'alaykum (there is no harm) implies its Prohibition.

Why do you practise it? They said: There is a man whose wife has to suckle the child, and if that person has a sexual intercourse with her (she may conceive) which he does not like, and there is another person who has a slave-girl and he has a sexual intercourse with her, but he does not like her to have conception so that she may not become Umm Walad, whereupon he (the Holy Prophet) said: There is no harm…

Mention was made about al-'azl in the presence of Allah's Messenger (ﷺ), whereupon he said: Why any one of you practises it? (He did not say: One of you should not do it), for there is no created soul, whose creator is not Allah.

The child does not come from all the liquid (sermen) and when Allah intends to create anything nothing can prevent it (from coming into existence).

"Why do you do that?" We said: "A man may have a wife, and he has intercourse with her, but he does not want her to get pregnant, or he may have a concubine, and he has intercourse with her, but he does not want her to get pregnant." He said: "It does not make any difference if you do that, for it is the matter of Al-Qadr."
