There’s no confusion. Islamic literature makes it perfectly clear:
"O Allah's Apostle! We get female captives as our share of booty, and we are interested in their prices, what is your opinion about coitus interruptus?" The Prophet said, "Do you really do that? It is better for you not to do it. No soul that which Allah has destined to exist, but will surely come into existence.” (Bukhari 34:432)
"We went out with Allah's Messenger (may peace be upon him) on the expedition to the Bi'l-Mustaliq and took captive some excellent Arab women; and we desired them, for we were suffering from the absence of our wives, (but at the same time) we also desired ransom for them. So we decided to have sexual intercourse with them but by observing 'azl (Withdrawing the male sexual organ before emission of semen to avoid-conception). But we said: We are doing an act whereas Allah's Messenger is amongst us; why not ask him? So we asked Allah's Messenger (may peace be upon him), and he said: It does not matter" (Sahih Muslim 3371)
