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 [Remember] when your Lord inspired to the angels, "I am with you, so strengthen those who have believed. I will cast terror into the hearts of those who disbelieved, so strike [them] upon the necks and strike from them every fingertip." 12 This, because they have resisted Allah and His apostle; and whosoever resisteth Allah and His apostle, then verily Allah is severe in retribution. 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 O ye who believe! When ye meet those who disbelieve in battle, turn not your backs to them. 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 You did not slay them, but God slew them; and when thou threwest, it was not thyself that threw, but God threw, and that He might confer on the believers a fair benefit; surely God is All-hearing, All-knowing. 17 That, and also because Allah is He Who makes feeble the plans and stratagem of the Unbelievers. 18 If ye besought a judgement then surely a judgement hath come unto you. And if ye desist it will be better for you; and if ye return We will return; and your host shall avail you not, although numerous it be; and know that verily Allah is with the believers. 19
