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 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, because they have cut themselves off from God and His Apostle: and as for him who cuts himself off from God and His Apostle - verily, God is severe in retribution. 13 That (is the award), so taste it, and (know) that for disbelievers is the torment 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 For he who turns his back on them on such ar occasion - except that it be for tactical reasons, or turning to join another company - he shall incur the wrath of Allah and Hell shall be his abode. It is an evil destination. 16 So the fact is that it was not you, but it was Allah Who killed them; and it was not you when you threw [sand at them], but it was Allah Who threw it, (and the believers were employed for the task) that He might cause the believers to successfully pass through this test. Allah is All-Hearing, All-Knowing. 17 That for you; and that God weakens the unbelievers' guile. 18 If you have been praying for victory, [O believers] - victory has now indeed come unto you. And if you abstain [from sinning,] it will be for your own good; but if you revert to it, We shall revoke [Our promise of aid] - and never will your community be of any avail to you, however great its numbers: for, behold, God is [only] with those who believe! 19
