[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 When thy Lord inspired the angels, (saying): I am with you. So make those who believe stand firm. I will throw fear into the hearts of those who disbelieve. Then smite the necks and smite of them each finger. 12 This because they contended against Allah and His Messenger: If any contend against Allah and His Messenger, Allah is strict in punishment. 13 "That [is yours], so taste it." And indeed for the disbelievers is the punishment of the Fire. 14 O ye who believe! when ye meet the Unbelievers in hostile array, never turn your backs to them. 15 For he who turns his back on them on such ar occasion - except that it be for tactical reasons, or turning to join another company - he shall incur the wrath of Allah and Hell shall be his abode. It is an evil destination. 16 You killed them not, but Allah killed them. And you (Muhammad SAW) threw not when you did throw but Allah threw, that He might test the believers by a fair trial from Him. Verily, Allah is All-Hearer, All-Knower. 17 This (is the fact) and surely, Allah weakens the deceitful plots of the disbelievers. 18 If ye besought a judgement then surely a judgement hath come unto you. And if ye desist it will be better for you; and if ye return We will return; and your host shall avail you not, although numerous it be; and know that verily Allah is with the believers. 19
