When two Muslims (confront each other) and the one amongst them attacks his brother with a weapon, both of them are at the brink of Hell-Fire. And when one of them kills his companion, both of them get into Hell-Fire.  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا الْمُسْلِمَانِ حَمَلَ أَحَدُهُمَا عَلَى أَخِيهِ السِّلاَحَ فَهُمَا فِي جُرُفِ جَهَنَّمَ فَإِذَا قَتَلَ أَحَدُهُمَا صَاحِبَهُ دَخَلاَهَا جَمِيعًا  

"If two Muslim men bear weapons against each other, then they are both on the brink of Hell. And if one of them kills the other, they will both be in Hell."  

إِذَا حَمَلَ الرَّجُلاَنِ الْمُسْلِمَانِ السِّلاَحَ أَحَدُهُمَا عَلَى الآخَرِ فَهُمَا عَلَى جُرُفِ جَهَنَّمَ فَإِذَا قَتَلَ أَحَدُهُمَا الآخَرَ فَهُمَا فِي النَّارِ  

“When one Muslim wields his weapon against his brother, both of them are at the edge of Hell, and if one of them kills the other, they will both enter it.”  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا الْمُسْلِمَانِ حَمَلَ أَحَدُهُمَا عَلَى أَخِيهِ السِّلاَحَ فَهُمَا عَلَى جُرُفِ جَهَنَّمَ فَإِذَا قَتَلَ أَحَدُهُمَا صَاحِبَهُ دَخَلاَهَا جَمِيعًا  

“When one Muslim wields his weapon against his brother, both of them are at the edge of Hell, and if one of them kills the other, they will both enter it.” (Using translation from Ibn Mājah 3965)   

"إذا الْتقى المسلمانِ حَمَلَ أحدهما على أخيه السلاح فهما على حرفِ جهنّمَ فإذا قَتَلَ أحدُهما صاحبَه دَخَلاها جميعًا" .  

“When one Muslim wields his weapon against his brother, both of them are at the edge of Hell, and if one of them kills the other, they will both enter it.” (Using translation from Ibn Mājah 3965)   

"إذا المسلمان حَملَ أحدُهما على أخيهِ السلاحَ فَهُما في جرَفُ جهنمَ فإذا قَتَلَ أحدُهما صاحبه دخلاها جميعًا" .
