Tribulations
36/11. Chapter:
When two Muslims confront one another with their swords
Sunan Ibn Majah
حَدَّثَنَا سُوَيْدُ بْنُ سَعِيدٍ، حَدَّثَنَا مُبَارَكُ بْنُ سُحَيْمٍ، عَنْ عَبْدِ الْعَزِيزِ بْنِ صُهَيْبٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، عَنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ قَالَ " مَا مِنْ مُسْلِمَيْنِ الْتَقَيَا بِأَسْيَافِهِمَا إِلاَّ كَانَ الْقَاتِلُ وَالْمَقْتُولُ فِي النَّارِ " .
It was narrated from Anas bin Malik that the Prophet (ﷺ) said: “There are no two Muslims who confront one another with their swords, but both the killer and the slain will be in Hell.”
