Sahih al-Bukhari 2229
Narrated Abu Sa`id Al-Khudri:
that while he was sitting with Allah's Messenger (ﷺ) he said, "O Allah's Messenger (ﷺ)! We get female captives as 
our share of booty, and we are interested in their prices, what is your opinion about coitus interrupt 
us?" The Prophet (ﷺ) 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.
حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي ابْنُ مُحَيْرِيزٍ، أَنَّ أَبَا سَعِيدٍ الْخُدْرِيَّ ـ رضى الله عنه ـ أَخْبَرَهُ أَنَّهُ، بَيْنَمَا هُوَ جَالِسٌ عِنْدَ النَّبِيِّ صلى الله عليه وسلم قَالَ يَا رَسُولَ اللَّهِ إِنَّا نُصِيبُ سَبْيًا، فَنُحِبُّ الأَثْمَانَ، فَكَيْفَ تَرَى فِي الْعَزْلِ فَقَالَ ‏
"‏ أَوَإِنَّكُمْ تَفْعَلُونَ ذَلِكَ لاَ عَلَيْكُمْ أَنْ لاَ تَفْعَلُوا ذَلِكُمْ، فَإِنَّهَا لَيْسَتْ نَسَمَةٌ كَتَبَ اللَّهُ أَنْ تَخْرُجَ إِلاَّ هِيَ خَارِجَةٌ ‏"‏‏.‏
