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 [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 This is the torment, so taste it, and surely for the disbelievers is the torment of the Fire. 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 For any one who turns his back on that day, except to manoeuvre or rally to his side, will bring the wrath of God on himself, and have Hell as abode; and what an evil destination! 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 Therefore take this, and (know that) Allah will weaken the scheme of the disbelievers. 18 O disbelievers! If you seek a judgement, then this judgement has come to you; and if you desist, it is better for you; and if you return to mischief, We will punish you again; and your populace will not benefit you, however large it may be – and besides this, Allah is with the Muslims. 19
