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 when Allah revealed to the angels, saying: 'I shall be with you. Give courage to the believers. I shall cast terror into the hearts of the unbelievers. Strike them above the necks, smite their finger tips' 12 This is because they opposed Allah and His Noble Messenger; and whoever opposes Allah and His Noble Messenger – then indeed Allah’s punishment is severe. 13 This! taste it then, and know that for the infidels is the torment of the Fire. 14 O you who believe! when you meet those who disbelieve marching for war, then turn not your backs to them. 15 (Whoever deserts the believers) will incur the wrath of God and will dwell in hell, a terrible dwelling. 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 Thus! And know that Allah weakeneth the contrivance of infidels. 18 If you (the pagans) are looking for conquest, you certainly had a great chance (at the battle of Badr). But if you were to give up such a desire, it would be better for you. If you again wage war against Us, We will be ready for such a confrontation. Your man-power will be of no help to you no matter how much you have; God is with the believers. 19
