A blanketing sleep came over you as a (measure of) security from Him, and He sent down rain from the skies to cleanse you, and to remove the plague of Satan, and to strengthen your hearts and steady your steps. 11 Remember thy Lord inspired the angels (with the message): "I am with you: give firmness to the Believers: I will instil terror into the hearts of the Unbelievers: smite ye above their necks and smite all their finger-tips off them." 12 they have opposed God and His Messengers." For those who oppose God and His Messengers, God has prepared a severe retribution. 13 That (is the award), so taste it, and (know) that for disbelievers is the torment of the Fire. 14 O ye who believe! When ye meet those who disbelieve in battle, turn not your backs to them. 15 Whoso on that day turneth his back to them, unless manoeuvring for battle or intent to join a company, he truly hath incurred wrath from Allah, and his habitation will be hell, a hapless journey's end. 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 how God causes the (evil) plans of the unbelievers to fail. 18 If you [disbelievers] seek the victory - the defeat has come to you. And if you desist [from hostilities], it is best for you; but if you return [to war], We will return, and never will you be availed by your [large] company at all, even if it should increase; and [that is] because Allah is with the believers. 19
