يَا أَيُّهَا الَّذِينَ آمَنُواْ إِذَا لَقِيتُمُ الَّذِينَ كَفَرُواْ زَحْفاً فَلاَ تُوَلُّوهُمُ الأَدْبَارَ
[8:15]
O you who believe! when you meet those who disbelieve marching for war, then turn not your backs to them.
O ye who believe! when ye meet the Unbelievers in hostile array, never turn your backs to them.
O ye who believe! When ye meet those who disbelieve in battle, turn not your backs to them.
