The Prophet [SAW] said: "If two Muslims confront each other with swords, each of them wanting to kill the other, they will both be in Hell." It was said to him: "O Messenger of Allah, (we understand about) the killer, but what about the one who is killed?" He said: "He was determined to kill his companion."
عَنِ النَّبِيِّ ﷺ قَالَ إِذَا تَوَاجَهَ الْمُسْلِمَانِ بِسَيْفَيْهِمَا كُلُّ وَاحِدٍ مِنْهُمَا يُرِيدُ قَتْلَ صَاحِبِهِ فَهُمَا فِي النَّارِ قِيلَ لَهُ يَا رَسُولَ اللَّهِ هَذَا الْقَاتِلُ فَمَا بَالُ الْمَقْتُولِ قَالَ إِنَّهُ كَانَ حَرِيصًا عَلَى قَتْلِ صَاحِبِهِ
