A blanketing sleep came over you as a (measure of) security from Him, and He sent down rain from the skies to cleanse you, and to remove the plague of Satan, and to strengthen your hearts and steady your steps. 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 they have opposed God and His Messengers." For those who oppose God and His Messengers, God has prepared a severe retribution. 13 For you is this (punishment) to taste, for the infidels the torment of Hell. 14 Believers, whenever you encounter a hostile force of unbelievers, do not turn your backs to them 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 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 That was that, but remember God will make the plots of the unbelievers contemptible. 18 (O disbelievers) if you ask for a judgement, now has the judgement come unto you and if you cease (to do wrong), it will be better for you, and if you return (to the attack), so shall We return, and your forces will be of no avail to you, however numerous it be, and verily, Allah is with the believers. 19
