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 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 That is your punishment (from Allah). So taste this punishment, and know that for the unbelievers is the punishment of the Fire. 14 O People who Believe! When you confront a large army of disbelievers in battle, do not turn your backs to them. 15 (Whoever deserts the believers) will incur the wrath of God and will dwell in hell, a terrible dwelling. 16 It was not you who killed them, but God did so. You did not throw what you threw, (sand into the eyes of the enemy at Badr), but God, to bring out the best in the faithful by doing them a favour of His own. God is all-hearing and all-knowing. 17 This is how God causes the (evil) plans of the unbelievers to fail. 18 (Tell the unbelievers:) 'If you have sought a judgement, then surely a judgement has come to you. And if you desist from disobedience, it is all the better for you. But if you revert to your mischief, We will again chastise you; and your host, howsoever numerous, will never be of any avail to you. Know well, Allah is with the believers.' 19
