[Remember] when He overwhelmed you with drowsiness [giving] security from Him and sent down upon you from the sky, rain by which to purify you and remove from you the evil [suggestions] of Satan and to make steadfast your hearts and plant firmly thereby your feet. 11 When your Lord commanded the angels, saying, "I am with you, so make those who believe stand firm. I will instill fear in the hearts of those who deny the truth: so strike their necks and strike all their finger joints!" 12 That is because they opposed Allah and His Messenger. And whoever opposes Allah and His Messenger - indeed, Allah is severe in penalty. 13 Therefore taste this for now, and along with it for the disbelievers is the punishment of fire. 14 O believers, when you encounter the unbelievers marching to battle, turn not your backs to them. 15 And whoever turns his back to them on such a day - unless it be a stratagem of war, or to retreat to a troop (of his own), - he indeed has drawn upon himself wrath from Allah. And his abode is Hell, and worst indeed is that destination! 16 It is not ye who slew them; it was Allah: when thou threwest (a handful of dust), it was not thy act, but Allah's: in order that He might test the Believers by a gracious trial from Himself: for Allah is He Who heareth and knoweth (all things). 17 This (is the fact) and surely, Allah weakens the deceitful plots of the disbelievers. 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
