From Sahih Muslim (Hadith 3553):
Abu Sa'id al-Khudri (Allah be pleased with him) reported: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
