[Remember how it was] when He caused inner calm to enfold you, as an assurance from Him, and sent down upon you water from the skies, so that He might purify you thereby and free you from Satan's unclean whisperings and strengthen your hearts and thus make firm your steps. 11 And recall what time thy Lord inspired the angels: verily I am with you, so keep firm those who have believed; I will cast horror into the hearts of those who have disbelieved, so smite them above the neck and smite of them every fingertip. 12 That was because they defied God and His Messenger. He who defies God and His Messenger shall be severely punished by God. 13 This [for you, O enemies of God]! Taste it, then, [and know] that suffering through fire awaits those who deny the truth! 14 O People who Believe! When you confront a large army of disbelievers in battle, do not turn your backs to them. 15 (Whoever deserts the believers) will incur the wrath of God and will dwell in hell, a terrible dwelling. 16 Ye (Muslims) slew them not, but Allah slew them. And thou (Muhammad) threwest not when thou didst throw, but Allah threw, that He might test the believers by a fair test from Him. Lo! Allah is Hearer, Knower. 17 That, and also because Allah is He Who makes feeble the plans and stratagem of the Unbelievers. 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
