Bukhari Volume 7, Book 62, Number 137: Narrated Abu Said Al-Khudri:

We got female captives in the war booty and we used to do coitus interruptus with them. So we asked Allah's Apostle about it and he said, "Do you really do that?" repeating the question thrice, "There is no soul that is destined to exist but will come into existence, till the Day of Resurrection."
[Coitus = During intercourse with woman when Man daws out his male organ from the female organ just before orgasm)
