When He was causing slumber to overcome you as a security from Him, and sending down on you water from heaven, to purify you thereby, and to put away from you the defilement of Satan, and to strengthen your hearts, and to confirm your feet. 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 was because they defied God and His Messenger. He who defies God and His Messenger shall be severely punished by God. 13 "That [is yours], so taste it." And indeed for the disbelievers is the punishment of the Fire. 14 O believers, when you meet unbelievers on the field of battle, do not turn your backs to them. 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 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 This is how God causes the (evil) plans of the unbelievers to fail. 18 (O Qureysh!) If ye sought a judgment, now hath the judgment come unto you. And if ye cease (from persecuting the believers) it will be better for you, but if ye return (to the attack) We also shall return. And your host will avail you naught, however numerous it be, and (know) that Allah is with the believers (in His Guidance). 19
