Recall what time He caused slumber to cover you as a security from Himself, and He sent down rain upon you from heaven that he might cleanse you thereby and take away from you the pollution of the Satan, and that he might gird up your hearts and make your feet firm thereby. 11 [Remember] when your Lord inspired to the angels, "I am with you, so strengthen those who have believed. I will cast terror into the hearts of those who disbelieved, so strike [them] upon the necks and strike from them every fingertip." 12 This is because they opposed Allah and His Noble Messenger; and whoever opposes Allah and His Noble Messenger – then indeed Allah’s punishment is severe. 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, whenever you encounter a hostile force of unbelievers, do not turn your backs to them in flight. 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 is how God causes the (evil) plans of the unbelievers to fail. 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
