[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 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 This is because they defied and disobeyed Allah and His Messenger. And whoever defies and disobeys Allah and His Messenger, then verily, Allah is Severe in punishment. 13 That is your punishment (from Allah). So taste this punishment, and know that for the unbelievers 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 whoever turns his back on such an occasion, unless it be as a stratagem of war, or in an endeavour to join another group [of the believers] will indeed draw down upon himself the wrath of God, and Hell shall be his abode and the worst indeed is that destination. 16 So the fact is that it was not you, but it was Allah Who killed them; and it was not you when you threw [sand at them], but it was Allah Who threw it, (and the believers were employed for the task) that He might cause the believers to successfully pass through this test. Allah is All-Hearing, All-Knowing. 17 that is what happened, and God will surely undermine the design of those who deny the truth. 18 You had asked for a judgement, so the judgement has come to you (In the form of victory for the faithful). So, if you desist it will be better for you. If you come back to it, We shall do the same, and your forces, however large, will not be of the least avail, for God is with those who believe. 19
