When He caused calm to fall on you as a security from Him and sent down upon you water from the cloud that He might thereby purify you, and take away from you the uncleanness of the Shaitan, and that He might fortify your hearts and steady (your) footsteps thereby. 11 [Remember] when your Lord inspired to the angels, "I am with you, so strengthen those who have believed. I will cast terror into the hearts of those who disbelieved, so strike [them] upon the necks and strike from them every fingertip." 12 That is because they opposed Allah and His Messenger. And whoever opposes Allah and His Messenger - indeed, Allah is severe in penalty. 13 Thus (will it be said): "Taste ye then of the (punishment): for those who resist Allah, is the penalty of the Fire." 14 Believers, when you encounter unbelievers on the march do not turn your backs to them in flight. 15 And on that day whoever turns his back to them, except for a battle strategy or to join one’s own company, has then turned towards Allah’s wrath, and his destination is hell; and what an evil place of return! 16 You did not slay them, but God slew them; and when thou threwest, it was not thyself that threw, but God threw, and that He might confer on the believers a fair benefit; surely 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 (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
