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 And recall when your Lord inspired the angels: 'I am certainly with you. So make firm the feet of those who believe. I will cast terror into the hearts of those who disbelieve. So strike at their necks and strike at every pore and tip. 12 That was because they defied God and His Messenger. He who defies God and His Messenger shall be severely punished by God. 13 We will say to them, "Endure the torment (as a consequence of your evil deeds); the unbelievers deserve nothing better than (the torment) of fire." 14 O you who believe! when you meet those who disbelieve marching for war, then turn not your backs to them. 15 And on that day whoever turns his back to them, except for a battle strategy or to join one’s own company, has then turned towards Allah’s wrath, and his destination is hell; and what an evil place of return! 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 Thus! And know that Allah weakeneth the contrivance of infidels. 18 (O Unbelievers!) if ye prayed for victory and judgment, now hath the judgment come to you: if ye desist (from wrong), it will be best for you: if ye return (to the attack), so shall We. Not the least good will your forces be to you even if they were multiplied: for verily Allah is with those who believe! 19
