Chapter 4: If Two Muslims Confront One Another With Their Swords
باب إِذَا تَوَاجَهَ الْمُسْلِمَانِ بِسَيْفَيْهِمَا
Sahih Muslim 157 i
Abu Huraira reported Allah's Messenger (ﷺ) many ahadith and one of them was this
The last Hour will not come until the two parties (of Muslims) confront each other and there is a large-scale massacre amongst them and the claim of both of them is the same.وَحَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، حَدَّثَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ، قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ تَقُومُ السَّاعَةُ حَتَّى تَقْتَتِلَ فِئَتَانِ عَظِيمَتَانِ وَتَكُونُ بَيْنَهُمَا مَقْتَلَةٌ عَظِيمَةٌ وَدَعْوَاهُمَا وَاحِدَةٌ " .
