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 [Remember] when your Lord inspired to the angels, "I am with you, so strengthen those who have believed. I will cast terror into the hearts of those who disbelieved, so strike [them] upon the necks and strike from them every fingertip." 12 That is because they opposed Allah and His Messenger. And whoever opposes Allah and His Messenger - indeed, Allah is severe in penalty. 13 That for you; therefore taste it; and that the chastisement of the Fire is for the unbelievers. 14 O ye who believe! when ye meet the Unbelievers in hostile array, never turn your backs to them. 15 Whoso turns his back that day to them, unless withdrawing to fight again or removing to join another host, he is laden with the burden of God's anger, and his refuge is Gehenna -- an evil homecoming! 16 It was not you (believers) but God who slew the pagans. It was not you (Muhammad) but God who threw dust at them. He did this as a favorable test for the believers. God is All-hearing and All-knowing. 17 That, and also because Allah is He Who makes feeble the plans and stratagem of the Unbelievers. 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
