“The Hour will not be established till two groups fight against each other, their claim being one and the same.”
Sahih Bukhari
حَدَّثَنَا عَلِيٌّ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا أَبُو الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ تَقُومُ السَّاعَةُ حَتَّى تَقْتَتِلَ فِئَتَانِ دَعْوَاهُمَا وَاحِدَةٌ ".
Narrated Abu Huraira: Allah's Messenger (ﷺ) said, "The Hour will not be established till two (huge) groups fight against each other, their claim being one and the same."
