"Abu Sirma said to Abu Sa'id al Khadri (Allah he pleased with him): 0 Abu Sa'id, did you hear Allah's Messenger (may peace be upon him) mentioning al-'azl? He said: Yes, and added: 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 Mes- senger (may peace be upon him), and he said: It does not matter if you do not do it, for every soul that is to be born up to the Day of Resurrection will be born."

Also, for your reading pleasure:

Or are you selective in what you choose to believe out of your Quran? Selective in what suits the political or military environment at any one time?__

Book 008, Number 3373:

"Abu Sa'id al-Khudri (Allah be pleased with him) reported: We took women captives, and we wanted to do 'azl with them. We then asked Allah's Messen- ger (may peace be upon him) about it, and he said to us: Verily you do it, verily you do it, verily you do it, but the soul which has to be born until the Day of judg- ment must be born."
