Al Hashr Ayah 14

لَا يُقَـٰتِلُونَكُمْ جَمِيعًا إِلَّا فِى قُرًى مُّحَصَّنَةٍ أَوْ مِن وَرَآءِ جُدُرِۭ‌ۚ بَأْسُهُم بَيْنَهُمْ شَدِيدٌ‌ۚ تَحْسَبُهُمْ جَمِيعًا وَقُلُوبُهُمْ شَتَّىٰ‌ۚ ذَٲلِكَ بِأَنَّهُمْ قَوْمٌ لَّا يَعْقِلُونَ ١٤ Even united, they would not ?dare? fight against you except ?from? within fortified strongholds or from behind walls. Their malice for each other is intense: you think they are united, yet their hearts are divided. That is because they are a people with no ?real? understanding.
