Abu Said al-Khudri (RA) reported that mention was made of azl in the presence of Allahs Apostle ﷺ whereupon he said: 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 if you do not do that, for that (the birth of the child) is something pre-ordained. Ibn Aun said: I made a mention of this hadith to Hasan, and he said: By Allah, (it seems) as if there is upbraiding in it (for azl).
