Sahih Muslim 1438 a
Abu Sirma said to Abu Sa'id al Khadri (Allah he pleased with him):
0 Abu Sa'id, did you hear Allah's Messenger (ﷺ) mentioning al-'azl? He said: Yes, and added: We went out with Allah's Messenger (ﷺ) 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 (ﷺ), 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.
وَحَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ، وَقُتَيْبَةُ بْنُ سَعِيدٍ، وَعَلِيُّ بْنُ حُجْرٍ، قَالُوا حَدَّثَنَا إِسْمَاعِيلُ، بْنُ جَعْفَرٍ أَخْبَرَنِي رَبِيعَةُ، عَنْ مُحَمَّدِ بْنِ يَحْيَى بْنِ حَبَّانَ، عَنِ ابْنِ مُحَيْرِيزٍ، أَنَّهُ قَالَ دَخَلْتُ أَنَا وَأَبُو صِرْمَةَ عَلَى أَبِي سَعِيدٍ الْخُدْرِيِّ فَسَأَلَهُ أَبُو صِرْمَةَ فَقَالَ يَا أَبَا سَعِيدٍ هَلْ سَمِعْتَ رَسُولَ اللَّهِ صلى الله عليه وسلم يَذْكُرُ الْعَزْلَ فَقَالَ نَعَمْ غَزَوْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم غَزْوَةَ بَلْمُصْطَلِقِ فَسَبَيْنَا كَرَائِمَ الْعَرَبِ فَطَالَتْ عَلَيْنَا الْعُزْبَةُ وَرَغِبْنَا فِي الْفِدَاءِ فَأَرَدْنَا أَنْ نَسْتَمْتِعَ وَنَعْزِلَ فَقُلْنَا نَفْعَلُ وَرَسُولُ اللَّهِ صلى الله عليه وسلم بَيْنَ أَظْهُرِنَا لاَ نَسْأَلُهُ ‏.‏ فَسَأَلْنَا رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَ ‏
"‏ لاَ عَلَيْكُمْ أَنْ لاَ تَفْعَلُوا مَا كَتَبَ اللَّهُ خَلْقَ نَسَمَةٍ هِيَ كَائِنَةٌ إِلَى يَوْمِ الْقِيَامَةِ إِلاَّ سَتَكُونُ ‏"‏ ‏.‏
