When you were overcome by sleep, as security from Him, He sent down water from the sky to cleanse you and to purify you of satan's filth, to strengthen your hearts and to steady your footsteps. 11 And when O dear Prophet, your Lord was inspiring the angels that, “I am with you – so make the believers stand firm; I will soon instil fear into the hearts of the disbelievers, so strike above the disbelievers’ necks and hit their each and every bone joint.” 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 Thus (will it be said): "Taste ye then of the (punishment): for those who resist Allah, is the penalty of the Fire." 14 Believers, whenever you encounter a hostile force of unbelievers, do not turn your backs to them in flight. 15 If any do turn his back to them on such a day - unless it be in a stratagem of war, or to retreat to a troop (of his own)- he draws on himself the wrath of Allah, and his abode is Hell,- an evil refuge (indeed)! 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 His manner of dealing with you. As for the unbelievers, Allah will surely undermine their designs. 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
