Remember He covered you with a sort of drowsiness, to give you calm as from Himself, and he caused rain to descend on you from heaven, to clean you therewith, to remove from you the stain of Satan, to strengthen your hearts, and to plant your feet firmly therewith. 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 That is because they opposed Allah and His Messenger. And whoever opposes Allah and His Messenger - indeed, Allah is severe in penalty. 13 Therefore taste this for now, and along with it for the disbelievers is the punishment of fire. 14 O you who believe! when you meet those who disbelieve marching for war, then turn not your backs to them. 15 If anyone on that day turns his back to them in flight, except when maneuvering to fight, or to join another party, he shall be laden with the Anger of Allah and Gehenna shall be his refuge an evil arrival. 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 [is so], and [also] that Allah will weaken the plot of the disbelievers. 18 If victory you are seeking, victory has already come upon you; and if you give over, it is better for you. But if you return, We shall return, and your host will avail you nothing though it be numerous; and that God is with the believers. 19
