ذِكْرُ الْعِلَّةِ الَّتِي مِنْ أَجْلِهَا تَلْعَنُ الْمَلَائِكَةَ هَذَا الْفَاعِلَ
[Machine] The Messenger of Allah ﷺ said: "If two Muslims meet and one of them kills his companion, then both of them will be in the Fire." Ahmad ibn Abdah also reported this hadith from another location, and Al-Mu'alla ibn Ziyad mentioned it as well.
قَالَ رَسُولُ اللَّهِ ﷺ «إِذَا الْتَقَى الْمُسْلِمَانِ فَقَتَلَ أَحَدُهُمَا صَاحِبَهُ فَهُمَا فِي النَّارِ» وَقَالَ أَحْمَدُ بْنُ عَبْدَةَ وَوَجَدْتُهُ فِي مَوْضِعٍ آخَرَ وَالْمُعَلَّى بْنُ زِيَادٍ
