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 recall what time thy Lord inspired the angels: verily I am with you, so keep firm those who have believed; I will cast horror into the hearts of those who have disbelieved, so smite them above the neck and smite of them every fingertip. 12 That is because they opposed Allah and His Messenger. And whoever opposes Allah and His Messenger - indeed, Allah is severe in penalty. 13 'That for you, so taste it, the punishment of the Fire is for the unbelievers' 14 Believers, do not retreat when facing the marching army of the unbelievers, for no believer will turn back at that time except for strategic reasons or to join another band. 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 You killed them not, but Allah killed them. And you (Muhammad SAW) threw not when you did throw but Allah threw, that He might test the believers by a fair trial from Him. Verily, Allah is All-Hearer, All-Knower. 17 That [is so], and [also] that Allah will weaken the plot of the disbelievers. 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
