When He was causing slumber to overcome you as a security from Him, and sending down on you water from heaven, to purify you thereby, and to put away from you the defilement of Satan, and to strengthen your hearts, and to confirm your feet. 11 And recall what time thy Lord inspired the angels: verily I am with you, so keep firm those who have believed; I will cast horror into the hearts of those who have disbelieved, so smite them above the neck and smite of them every fingertip. 12 For they had opposed God and His Apostle; but whosoever opposes God and his Apostle (should know) that God is severe in retribution. 13 That (is the award), so taste it, and (know) that for disbelievers is the torment of the Fire. 14 O believers, when you meet unbelievers on the field of battle, do not turn your backs to them. 15 For any one who turns his back on that day, except to manoeuvre or rally to his side, will bring the wrath of God on himself, and have Hell as abode; and what an evil 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 [was God's purpose] - and also [to show] that God renders vain the artful schemes of those who deny the truth. 18 O disbelievers! If you seek a judgement, then this judgement has come to you; and if you desist, it is better for you; and if you return to mischief, We will punish you again; and your populace will not benefit you, however large it may be – and besides this, Allah is with the Muslims. 19
