When He made the slumber fall upon you as a reassurance from him and sent down water from the sky upon you, that thereby He might purify you, and remove from you the fear of Satan, and make strong your hearts and firm (your) feet thereby. 11 When your Lord revealed to the angels: I am with you, therefore make firm those who believe. I will cast terror into the hearts of those who disbelieve. Therefore strike off their heads and strike off every fingertip of them. 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 This is the torment, so taste it, and surely for the disbelievers is the torment of the 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 Wherefore ye slew them not, but Allah slew them, and thou threwest not, when thou threwest, but Allah threw, in order that He might prove the believers with a goodly proving from Him. Verily Allah is Hearing, Knowing. 17 That (is the case); and (know) that Allah (it is) Who maketh weak the plan of 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
