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 When thy Lord inspired the angels, (saying): I am with you. So make those who believe stand firm. I will throw fear into the hearts of those who disbelieve. Then smite the necks and smite of them each finger. 12 This because they contended against Allah and His Messenger: If any contend against Allah and His Messenger, Allah is strict in punishment. 13 That is your punishment, taste it then; and know that for those who deny the truth there is the punishment of the Fire. 14 Believers, when you encounter unbelievers on the march do not turn your backs to them in flight. 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 And you did not kill them, but it was Allah who killed them. And you threw not, [O Muhammad], when you threw, but it was Allah who threw that He might test the believers with a good test. Indeed, Allah is Hearing and Knowing. 17 This is His manner of dealing with you. As for the unbelievers, Allah will surely undermine their designs. 18 If victory you are seeking, victory has already come upon you; and if you give over, it is better for you. But if you return, We shall return, and your host will avail you nothing though it be numerous; and that God is with the believers. 19
