When you were overcome by sleep, as security from Him, He sent down water from the sky to cleanse you and to purify you of satan's filth, to strengthen your hearts and to steady your footsteps. 11 And recall what time thy Lord inspired the angels: verily I am with you, so keep firm those who have believed; I will cast horror into the hearts of those who have disbelieved, so smite them above the neck and smite of them every fingertip. 12 This is because they acted adversely to Allah and His Apostle; and whoever acts adversely to Allah and His Apostle-- then surely Allah is severe in requiting (evil). 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 If any do turn his back to them on such a day - unless it be in a stratagem of war, or to retreat to a troop (of his own)- he draws on himself the wrath of Allah, and his abode is Hell,- an evil refuge (indeed)! 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 This is how God causes the (evil) plans of the unbelievers to fail. 18 If you were seeking a victory, victory has now come to you. If you desist, it will be better for you. If you resume We will return, and even if your forces are numerous, they shall not help you at all. And Allah is with the believers. 19
