When you were overcome by sleep, as security from Him, He sent down water from the sky to cleanse you and to purify you of satan's filth, to strengthen your hearts and to steady your footsteps. 11 Your Lord inspired the angels saying, "I am with you. Encourage the believers. I shall cast terror into the hearts of the unbelievers and you will strike their heads and limbs; 12 That is because they opposed Allah and His Messenger. And whoever opposes Allah and His Messenger - indeed, Allah is severe in penalty. 13 This-- taste it, and (know) that for the unbelievers is the chastisement of fire. 14 O Ye who believe! whenever ye meet those who disbelieve marching slowly turn to them not your backs. 15 And whoever shall turn his back to them on that day-- unless he turn aside for the sake of fighting or withdraws to a company-- then he, indeed, becomes deserving of Allah's wrath, and his abode is hell; and an evil destination shall it be. 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 His manner of dealing with you. As for the unbelievers, Allah will surely undermine their designs. 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
