When He was causing slumber to overcome you as a security from Him, and sending down on you water from heaven, to purify you thereby, and to put away from you the defilement of Satan, and to strengthen your hearts, and to confirm your feet. 11 And recall what time thy Lord inspired the angels: verily I am with you, so keep firm those who have believed; I will cast horror into the hearts of those who have disbelieved, so smite them above the neck and smite of them every fingertip. 12 This is because they had made a breach with Allah and His Messenger. He who makes a breach with Allah and His Messenger indeed, Allah is stern in retribution. 13 For you is this (punishment) to taste, for the infidels the torment of Hell. 14 O you who believe! when you meet those who disbelieve marching for war, then turn not your backs to them. 15 If any do turn his back to them on such a day - unless it be in a stratagem of war, or to retreat to a troop (of his own)- he draws on himself the wrath of Allah, and his abode is Hell,- an evil refuge (indeed)! 16 So you did not slay them, but it was Allah Who slew them, and you did not smite when you smote (the enemy), but it was Allah Who smote, and that He might confer upon the believers a good gift from Himself; surely Allah is Hearing, Knowing. 17 This is His manner of dealing with you. As for the unbelievers, Allah will surely undermine their designs. 18 If you were seeking a judgement, a judgement has now come to you. If you desist, it will be the better for you. But if you return [to hostility] We too will return. And your host will avail you naught, however numerous it may be, and [know] that surely God is with the believers. 19
