Surah Al-Hashr, ayah 14

59:14

لَا يُقَٰتِلُونَكُمۡ جَمِيعًا إِلَّا فِي قُرٗى مُّحَصَّنَةٍ أَوۡ مِن وَرَآءِ جُدُرِۭۚ بَأۡسُهُم بَيۡنَهُمۡ شَدِيدٞۚ تَحۡسَبُهُمۡ جَمِيعٗا وَقُلُوبُهُمۡ شَتَّىٰۚ ذَٰلِكَ بِأَنَّهُمۡ قَوۡمٞ لَّا يَعۡقِلُونَ ١٤

Lā yuqātilūnakum jamī'an illā fī quram muhassanatin aw min warā'i juduri ba suhum baynahum shadīdun tahsabuhum jamī'an waqulūbuhum shattā dhālika bi annahum qawmul lā ya'qilūn

They will not fight you all except within fortified cities or from behind walls. Their violence [i.e., enmity] among themselves is severe. You think they are together, but their hearts are diverse. That is because they are a people who do not reason.
