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 When thy Lord was revealing to the angels, 'I am with you; so confirm the believers. I shall cast into the unbelievers' hearts terror; so smite above the necks, and smite every finger of them!' 12 they have opposed God and His Messengers." For those who oppose God and His Messengers, God has prepared a severe retribution. 13 For you is this (punishment) to taste, for the infidels the torment of Hell. 14 O you who believe! when you meet those who disbelieve marching for war, then turn not your backs to them. 15 And whoever shall turn his back to them on that day-- unless he turn aside for the sake of fighting or withdraws to a company-- then he, indeed, becomes deserving of Allah's wrath, and his abode is hell; and an evil destination shall it be. 16 Wherefore ye slew them not, but Allah slew them, and thou threwest not, when thou threwest, but Allah threw, in order that He might prove the believers with a goodly proving from Him. Verily Allah is Hearing, Knowing. 17 That [is so], and [also] that Allah will weaken the plot of the disbelievers. 18 If you were seeking a victory, victory has now come to you. If you desist, it will be better for you. If you resume We will return, and even if your forces are numerous, they shall not help you at all. And Allah is with the believers. 19
