Surah Al-Hashr Verse 14 - English Translation by Ali Unal
Surah Al-Hashrلَا يُقَٰتِلُونَكُمۡ جَمِيعًا إِلَّا فِي قُرٗى مُّحَصَّنَةٍ أَوۡ مِن وَرَآءِ جُدُرِۭۚ بَأۡسُهُم بَيۡنَهُمۡ شَدِيدٞۚ تَحۡسَبُهُمۡ جَمِيعٗا وَقُلُوبُهُمۡ شَتَّىٰۚ ذَٰلِكَ بِأَنَّهُمۡ قَوۡمٞ لَّا يَعۡقِلُونَ
They will never fight against you as a united body (in alliance with the Hypocrites, with the Jews of Khaybar and others), unless it be from within fortified strongholds or from behind high walls. Severe is their belligerent discord among themselves (except when not opportunistically allied in warfare against you). You think of them as one body, but in fact their hearts are at odds with one another: This is because they are a people who do not reason (and come to an understanding of the situations they face)
