A blanketing sleep came over you as a (measure of) security from Him, and He sent down rain from the skies to cleanse you, and to remove the plague of Satan, and to strengthen your hearts and steady your steps. 11 And when Allah revealed to the angels, saying: 'I shall be with you. Give courage to the believers. I shall cast terror into the hearts of the unbelievers. Strike them above the necks, smite their finger tips' 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 your punishment (from Allah). So taste this punishment, and know that for the unbelievers is the punishment of the Fire. 14 Believers, when you encounter unbelievers on the march do not turn your backs to them in flight. 15 And whosoever turneth his back to them on such a day, unless it be swerving to a fight or wriggling round to company, hath surely drawn upon himself indignation from Allah, and his resort is Hell - an evil destination! 16 And yet, [O believers,] it was not you who slew the enemy, but it was God who slew them; and it was not thou who cast [terror into them, O Prophet,] when thou didst cast it, but it was God who cast it: and [He did all this] in order that He might test the believers by a goodly test of His Own ordaining. Verily, God is all-hearing, all-knowing! 17 That, and also because Allah is He Who makes feeble the plans and stratagem of the Unbelievers. 18 If you [disbelievers] seek the victory - the defeat has come to you. And if you desist [from hostilities], it is best for you; but if you return [to war], We will return, and never will you be availed by your [large] company at all, even if it should increase; and [that is] because Allah is with the believers. 19
