Remember He covered you with a sort of drowsiness, to give you calm as from Himself, and he caused rain to descend on you from heaven, to clean you therewith, to remove from you the stain of Satan, to strengthen your hearts, and to plant your feet firmly therewith. 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 That is because they opposed Allah and His messenger. Whoso opposeth Allah and His messenger, (for him) lo! Allah is severe in punishment. 13 That for you; therefore taste it; and that the chastisement of the Fire is for the unbelievers. 14 Believers, do not retreat when facing the marching army of the unbelievers, for no believer will turn back at that time except for strategic reasons or to join another band. 15 for, whoever on that day turns his back on them - unless it be in a battle manoeuvre or in an endeavour to join another troop [of the believers] - shall indeed have earned the burden of God's condemnation, and his goal shall be hell: and how vile a journey's end! 16 You did not kill them; it was God who killed them; and when you [Prophet] threw [sand] at them it was not you, but God who threw it so that He might confer on the believers a great favour from Himself. Surely, God is all hearing, all-knowing, 17 That [is so], and [also] that Allah will weaken the plot of the disbelievers. 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
