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 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 We will say to them, "Endure the torment (as a consequence of your evil deeds); the unbelievers deserve nothing better than (the torment) of fire." 14 Believers, when you encounter unbelievers on the march do not turn your backs to them in flight. 15 If any do turn his back to them on such a day - unless it be in a stratagem of war, or to retreat to a troop (of his own)- he draws on himself the wrath of Allah, and his abode is Hell,- an evil refuge (indeed)! 16 It was not you who killed them, but God did so. You did not throw what you threw, (sand into the eyes of the enemy at Badr), but God, to bring out the best in the faithful by doing them a favour of His own. God is all-hearing and all-knowing. 17 That, and also because Allah is He Who makes feeble the plans and stratagem of the Unbelievers. 18 If you were seeking a judgement, a judgement has now come to you. If you desist, it will be the better for you. But if you return [to hostility] We too will return. And your host will avail you naught, however numerous it may be, and [know] that surely God is with the believers. 19
