"O you who believe, when you meet those who disbelieve marching for war, turn not your backs to them. And whoso turns his back to them on that day unless manoeuvring for battle or turning to join a company -- he, indeed, incurs God's wrath and his refuge is Hell. And an evil destination it is. Because you slew them not, but God didst slay them, and thou smotest not when thou didst smite (the enemy), but God didst smite (him), and that He might confer upon the believers a benefit from Himself. Surely God who heareth and knoweth (all things). This -- and (know) that God will weaken the struggle of the disbelievers."
