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 And when Allah revealed to the angels, saying: 'I shall be with you. Give courage to the believers. I shall cast terror into the hearts of the unbelievers. Strike them above the necks, smite their finger tips' 12 This is because they defied and disobeyed Allah and His Messenger. And whoever defies and disobeys Allah and His Messenger, then verily, Allah is Severe in punishment. 13 'That for you, so taste it, the punishment of the Fire is for the unbelievers' 14 O you who have believed, when you meet those who disbelieve advancing [for battle], do not turn to them your backs [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 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 Therefore take this, and (know that) Allah will weaken the scheme 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
