(Remember) when He covered you with a slumber as a security from Him, and He caused water (rain) to descend on you from the sky, to clean you thereby and to remove from you the Rijz (whispering, evil-suggestions, etc.) of Shaitan (Satan), and to strengthen your hearts, and make your feet firm thereby. 11 And the Lord said to the angels: "I am with you; go and strengthen the faithful. I shall fill the hearts of infidels with terror. So smite them on their necks and every joint, (and incapacitate them)," 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 For you is this (punishment) to taste, for the infidels the torment of Hell. 14 O you who believe! when you meet those who disbelieve marching for war, then turn not your backs to 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 God did so. You did not throw what you threw, (sand into the eyes of the enemy at Badr), but God, to bring out the best in the faithful by doing them a favour of His own. God is all-hearing and all-knowing. 17 This (is the fact) and surely, Allah weakens the deceitful plots of the disbelievers. 18 If you were seeking a judgement, a judgement has now come to you. If you desist, it will be the better for you. But if you return [to hostility] We too will return. And your host will avail you naught, however numerous it may be, and [know] that surely God is with the believers. 19
