When He made the slumber overcome you, so it was as a peacefulness from Him, and sent down water from the sky upon you to purify you with it, and to remove the impurity of Satan from you, and to give your hearts fortitude and firmly establish your feet with it. 11 Remember thy Lord inspired the angels (with the message): "I am with you: give firmness to the Believers: I will instil terror into the hearts of the Unbelievers: smite ye above their necks and smite all their finger-tips off them." 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 This is the torment, so taste it, and surely for the 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 And whoever turns his back to them on such a day, unless swerving [as a strategy] for war or joining [another] company, has certainly returned with anger [upon him] from Allah, and his refuge is Hell - and wretched is the destination. 16 It was not you who killed them, but Allah slew them, neither was it you who threw at them. Allah threw at them in order that He confers on the believers a fair benefit. Indeed, Allah is Hearing, Knowing. 17 That (is the case); and (know) that Allah (it is) Who maketh weak the plan of disbelievers. 18 (O Qureysh!) If ye sought a judgment, now hath the judgment come unto you. And if ye cease (from persecuting the believers) it will be better for you, but if ye return (to the attack) We also shall return. And your host will avail you naught, however numerous it be, and (know) that Allah is with the believers (in His Guidance). 19
