[Remember how it was] when He caused inner calm to enfold you, as an assurance from Him, and sent down upon you water from the skies, so that He might purify you thereby and free you from Satan's unclean whisperings and strengthen your hearts and thus make firm your steps. 11 And the Lord said to the angels: "I am with you; go and strengthen the faithful. I shall fill the hearts of infidels with terror. So smite them on their necks and every joint, (and incapacitate them)," 12 For they had opposed God and His Apostle; but whosoever opposes God and his Apostle (should know) that God is severe in retribution. 13 Thus (will it be said): "Taste ye then of the (punishment): for those who resist Allah, is the penalty 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 Whoso on that day turneth his back to them, unless manoeuvring for battle or intent to join a company, he truly hath incurred wrath from Allah, and his habitation will be hell, a hapless journey's end. 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 how God causes the (evil) plans of the unbelievers to fail. 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
