Arabic (Original)
حَدَّثَنَا مُؤَمَّلٌ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ أَخْبَرَنَا أَيُّوبُ وَيُونُسُ وَهِشَامٌ وَالْمُعَلَّي بْنُ زِيَادٍ عَن الْحَسَنِ عَن الْأَحْنَفِ عَن أَبِي بَكْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا تَوَاجَهَ الْمُسْلِمَانِ بِسَيْفَيْهِمَا فَقَتَلَ أَحَدُهُمَا صَاحِبَهُ فَهُمَا فِي النَّارِ جَمِيعًا.
