Al-Hashr · Ayah 14
لَا يُقَٰتِلُونَكُمْ جَمِيعًا إِلَّا فِى قُرًى مُّحَصَّنَةٍ أَوْ مِن وَرَآءِ جُدُرٍۭ بَأْسُهُم بَيْنَهُمْ شَدِيدٌ تَحْسَبُهُمْ جَمِيعًا وَقُلُوبُهُمْ شَتَّىٰ ذَٰلِكَ بِأَنَّهُمْ قَوْمٌ لَّا يَعْقِلُونَ
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.
