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 ".

It is better for you not to do it. No soul that which Allah has destined to exist, but will surely come into existence.
