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 When thy Lord was revealing to the angels, 'I am with you; so confirm the believers. I shall cast into the unbelievers' hearts terror; so smite above the necks, and smite every finger of them!' 12 This because they contended against Allah and His Messenger: If any contend against Allah and His Messenger, Allah is strict in punishment. 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 the Unbelievers in hostile array, never turn your backs to them. 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 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 so], and [also] that Allah will weaken the plot of the 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
