When He was causing slumber to overcome you as a security from Him, and sending down on you water from heaven, to purify you thereby, and to put away from you the defilement of Satan, and to strengthen your hearts, and to confirm your feet. 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 For they had opposed God and His Apostle; but whosoever opposes God and his Apostle (should know) that God is severe in retribution. 13 That for you; therefore taste it; and that the chastisement of the Fire is for the unbelievers. 14 Believers, when you meet in battle those who deny the truth, never turn your backs on them: 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 who killed them, but Allah slew them, neither was it you who threw at them. Allah threw at them in order that He confers on the believers a fair benefit. Indeed, Allah is Hearing, Knowing. 17 This, and that Allah is the weakener of the struggle of the unbelievers. 18 If you (the pagans) are looking for conquest, you certainly had a great chance (at the battle of Badr). But if you were to give up such a desire, it would be better for you. If you again wage war against Us, We will be ready for such a confrontation. Your man-power will be of no help to you no matter how much you have; God is with the believers. 19
