أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّی قَالَ حَدَّثَنَا الْخَلِيلُ بْنُ عُمَرَ بْنِ إِبْرَاهِيمَ قَالَ حَدَّثَنِي أَبِي قَالَ حَدَّثَنِي قَتَادَةُ عَنْ الْحَسَنِ عَنْ أَبِي بَکْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا الْتَقَی الْمُسْلِمَانِ بِسَيْفَيْهِمَا فَقَتَلَ أَحَدُهُمَا صَاحِبَهُ فَالْقَاتِلُ وَالْمَقْتُولُ فِي النَّارِ
