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 That is because they opposed Allah and His Messenger. And whoever opposes Allah and His Messenger - indeed, Allah is severe in penalty. 13 This-- taste it, and (know) that for the unbelievers is the chastisement of fire. 14 Believers, when you meet in battle those who deny the truth, never turn your backs on 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 It was not you (believers) but God who slew the pagans. It was not you (Muhammad) but God who threw dust at them. He did this as a favorable test for the believers. God is All-hearing and All-knowing. 17 That was that, but remember God will make the plots of the unbelievers contemptible. 18 (O Unbelievers!) if ye prayed for victory and judgment, now hath the judgment come to you: if ye desist (from wrong), it will be best for you: if ye return (to the attack), so shall We. Not the least good will your forces be to you even if they were multiplied: for verily Allah is with those who believe! 19
