صحيح البخاري

Narrated Abu Sa`id Al-Khudri:

That while he was sitting with the Prophet (ﷺ) a man from the Ansar came and said, "O Allah's Messenger! We get slave girls from the war captives and we love property; what do you think about coitus interruptus?" Allah's Messenger (ﷺ) said, "Do you do that? It is better for you not to do it, for there is no soul which Allah has ordained to come into existence but will be created."
