He brought drowsiness upon you to give you His reassurance and sent down water from the sky upon you, so that He might thereby purify you and remove Satan's pollution from you, and make your hearts strong and your feet firm. 11 And when O dear Prophet, your Lord was inspiring the angels that, “I am with you – so make the believers stand firm; I will soon instil fear into the hearts of the disbelievers, so strike above the disbelievers’ necks and hit their each and every bone joint.” 12 That, because they had made a breach with God and with His Messenger; and whosoever makes a breach with God and with His Messenger, surely God is terrible in retribution. 13 Therefore taste this for now, and along with it for the disbelievers is the punishment of fire. 14 Believers, whenever you encounter a hostile force of unbelievers, do not turn your backs to them in flight. 15 whoever turns his back on such an occasion, unless it be as a stratagem of war, or in an endeavour to join another group [of the believers] will indeed draw down upon himself the wrath of God, and Hell shall be his abode and the worst indeed is that destination. 16 It was not you (believers) but God who slew the pagans. It was not you (Muhammad) but God who threw dust at them. He did this as a favorable test for the believers. God is All-hearing and All-knowing. 17 That was that, but remember God will make the plots of the unbelievers contemptible. 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
