(Remember) when He covered you with a slumber as a security from Him, and He caused water (rain) to descend on you from the sky, to clean you thereby and to remove from you the Rijz (whispering, evil-suggestions, etc.) of Shaitan (Satan), and to strengthen your hearts, and make your feet firm thereby. 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 acted adversely to Allah and His Apostle; and whoever acts adversely to Allah and His Apostle-- then surely Allah is severe in requiting (evil). 13 This [for you, O enemies of God]! Taste it, then, [and know] that suffering through fire awaits those who deny the truth! 14 O believers, when you encounter the unbelievers marching to battle, 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 It was not you who killed them, but Allah slew them, neither was it you who threw at them. Allah threw at them in order that He confers on the believers a fair benefit. Indeed, Allah is Hearing, Knowing. 17 Thus! And know that Allah weakeneth the contrivance of infidels. 18 If you were seeking a victory, victory has now come to you. If you desist, it will be better for you. If you resume We will return, and even if your forces are numerous, they shall not help you at all. And Allah is with the believers. 19
