When He made the slumber fall upon you as a reassurance from him and sent down water from the sky upon you, that thereby He might purify you, and remove from you the fear of Satan, and make strong your hearts and firm (your) feet thereby. 11 Your Lord inspired the angels saying, "I am with you. Encourage the believers. I shall cast terror into the hearts of the unbelievers and you will strike their heads and limbs; 12 This is because they defied Allah and His Messenger. Whoever defies Allah and His Messenger must know that Allah is severe in punishment. 13 This [for you, O enemies of God]! Taste it, then, [and know] that suffering through fire awaits those who deny the truth! 14 Believers, when you encounter unbelievers on the march do not turn your backs to them in flight. 15 (Whoever deserts the believers) will incur the wrath of God and will dwell in hell, a terrible dwelling. 16 Wherefore ye slew them not, but Allah slew them, and thou threwest not, when thou threwest, but Allah threw, in order that He might prove the believers with a goodly proving from Him. Verily Allah is Hearing, Knowing. 17 That for you; and that God weakens the unbelievers' guile. 18 If you were seeking a judgement, a judgement has now come to you. If you desist, it will be the better for you. But if you return [to hostility] We too will return. And your host will avail you naught, however numerous it may be, and [know] that surely God is with the believers. 19
