[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 when O dear Prophet, your Lord was inspiring the angels that, “I am with you – so make the believers stand firm; I will soon instil fear into the hearts of the disbelievers, so strike above the disbelievers’ necks and hit their each and every bone joint.” 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 the award), so taste it, and (know) that for disbelievers is the torment of the Fire. 14 O Ye who believe! whenever ye meet those who disbelieve marching slowly turn to them not your backs. 15 for, whoever on that day turns his back on them - unless it be in a battle manoeuvre or in an endeavour to join another troop [of the believers] - shall indeed have earned the burden of God's condemnation, and his goal shall be hell: and how vile a journey's end! 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 Allah will surely weaken the guile of the unbelievers. 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
