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 That is because they opposed Allah and His messenger. Whoso opposeth Allah and His messenger, (for him) lo! Allah is severe in punishment. 13 For you is this (punishment) to taste, for the infidels the torment of Hell. 14 O People who Believe! When you confront a large army of disbelievers in battle, do not turn your backs to them. 15 Whoso turns his back that day to them, unless withdrawing to fight again or removing to join another host, he is laden with the burden of God's anger, and his refuge is Gehenna -- an evil homecoming! 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 This, and that Allah is the weakener of the struggle of the unbelievers. 18 (Tell the unbelievers:) 'If you have sought a judgement, then surely a judgement has come to you. And if you desist from disobedience, it is all the better for you. But if you revert to your mischief, We will again chastise you; and your host, howsoever numerous, will never be of any avail to you. Know well, Allah is with the believers.' 19
