When He made the slumber overcome you, so it was as a peacefulness from Him, and sent down water from the sky upon you to purify you with it, and to remove the impurity of Satan from you, and to give your hearts fortitude and firmly establish your feet with it. 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 That is because they opposed Allah and His Messenger. And whoever opposes Allah and His Messenger - indeed, Allah is severe in penalty. 13 This is the torment, so taste it, and surely for the disbelievers is the torment of the Fire. 14 O you who believe! When you meet those who disbelieve, in a battle-field, never turn your backs to them. 15 Whoso turns his back that day to them, unless withdrawing to fight again or removing to join another host, he is laden with the burden of God's anger, and his refuge is Gehenna -- an evil homecoming! 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 Allah will surely weaken the guile of the unbelievers. 18 If ye besought a judgement then surely a judgement hath come unto you. And if ye desist it will be better for you; and if ye return We will return; and your host shall avail you not, although numerous it be; and know that verily Allah is with the believers. 19
