[Remember] when He overwhelmed you with drowsiness [giving] security from Him and sent down upon you from the sky, rain by which to purify you and remove from you the evil [suggestions] of Satan and to make steadfast your hearts and plant firmly thereby your feet. 11 When thy Lord was revealing to the angels, 'I am with you; so confirm the believers. I shall cast into the unbelievers' hearts terror; so smite above the necks, and smite every finger of them!' 12 That, because they had made a breach with God and with His Messenger; and whosoever makes a breach with God and with His Messenger, surely God is terrible in retribution. 13 That is your punishment, taste it then; and know that for those who deny the truth there is the punishment of the Fire. 14 O ye who believe! When ye meet those who disbelieve in battle, turn not your backs to them. 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 Wherefore ye slew them not, but Allah slew them, and thou threwest not, when thou threwest, but Allah threw, in order that He might prove the believers with a goodly proving from Him. Verily Allah is Hearing, Knowing. 17 That [is so], and [also] that Allah will weaken the plot of the disbelievers. 18 If victory you are seeking, victory has already come upon you; and if you give over, it is better for you. But if you return, We shall return, and your host will avail you nothing though it be numerous; and that God is with the believers. 19
