Arabic (Original)
حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا مَعْمَرٌ عَنْ قَتَادَةَ عَنِ الْحَسَنِ عَنْ أَبِي بَكْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا تَوَاجَهَ الْمُسْلِمَانِ بِسَيْفَيْهِمَا فَقَتَلَ أَحَدُهُمَا صَاحِبَهُ فَالْقَاتِلُ وَالْمَقْتُولُ فِي النَّارِ قَالُوا يَا رَسُولَ اللَّهِ هَذَا الْقَاتِلُ فَمَا بَالُ الْمَقْتُولِ قَالَ إِنَّهُ كَانَ يُرِيدُ قَتْلَ صَاحِبِهِ.
English Translation
Abd al-Razzaq told us, Ma'mar informed us, from Qatadah, from al-Hasan, from Abu Bakrah, who said: The Messenger of Allah, peace and blessings be upon him, said: "When two Muslims face each other with their swords, and one of them kills the other, then both the killer and the killed are in the Fire." They said: "O Messenger of Allah, this is the killer, but what about the one killed?" He said: "He intended to kill his companion."
