“When two Muslims confront one another with their swords, both the killer and the slain will be in Hell.” They said: “O Messenger of Allah, (we understand about) this killer, but what is wrong with the one who is slain?” He said: “He wanted to kill his companion.’” (Using translation from Ibn Mājah 3964)
قَالَ رَسُولُ اللهِ ﷺ إِذَا تَوَاجَهَ الْمُسْلِمَانِ بِسَيْفَيْهِمَا وَكِلَاهُمَا يُرِيدُ أَنْ يَقْتُلَ صَاحِبَهُ فَقَتَلَ أَحَدُهُمَا الْآخَرَ فَهُمَا فِي النَّارِ قِيلَ يَا رَسُولَ اللهِ هَذَا الْقَاتِلُ فَمَا بَالُ الْمَقْتُولِ؟ قَالَ لِأَنَّهُ أَرَادَ قَتْلَ صَاحِبِهِ
