أَخْبَرَنَا أَحْمَدُ بْنُ عَبْدَةَ، عَنْ حَمَّادٍ، عَنْ أَيُّوبَ، وَيُونُسَ، وَالْعَلاَءِ بْنِ زِيَادٍ، عَنِ الْحَسَنِ، عَنِ الأَحْنَفِ بْنِ قَيْسٍ، عَنْ أَبِي بَكْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ إِذَا الْتَقَى الْمُسْلِمَانِ بِسَيْفَيْهِمَا فَقَتَلَ أَحَدُهُمَا صَاحِبَهُ فَالْقَاتِلُ وَالْمَقْتُولُ فِي النَّارِ ‏"‏ ‏.‏
