حَدَّثَنَاه أَحْمَدُ بْنُ عَبْدَةَ الضَّبِّيُّ حَدَّثَنَا حَمَّادٌ عَنْ أَيُّوبَ وَيُونُسَ وَالْمُعَلَّی بْنِ زِيَادٍ عَنْ الْحَسَنِ عَنْ الْأَحْنَفِ بْنِ قَيْسٍ عَنْ أَبِي بَکْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا الْتَقَی الْمُسْلِمَانِ بِسَيْفَيْهِمَا فَالْقَاتِلُ وَالْمَقْتُولُ فِي النَّارِ
