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 And recall when your Lord inspired the angels: 'I am certainly with you. So make firm the feet of those who believe. I will cast terror into the hearts of those who disbelieve. So strike at their necks and strike at every pore and tip. 12 That is because they opposed Allah and His messenger. Whoso opposeth Allah and His messenger, (for him) lo! Allah is severe in punishment. 13 That is your punishment, taste it then; and know that for those who deny the truth there is the punishment of the Fire. 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 You killed them not, but Allah killed them. And you (Muhammad SAW) threw not when you did throw but Allah threw, that He might test the believers by a fair trial from Him. Verily, Allah is All-Hearer, All-Knower. 17 This (is the fact) and surely, Allah weakens the deceitful plots of the disbelievers. 18 (O disbelievers) if you ask for a judgement, now has the judgement come unto you and if you cease (to do wrong), it will be better for you, and if you return (to the attack), so shall We return, and your forces will be of no avail to you, however numerous it be, and verily, Allah is with the believers. 19
