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 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 That was because they defied God and His Messenger. He who defies God and His Messenger shall be severely punished by God. 13 This [for you, O enemies of God]! Taste it, then, [and know] that suffering through fire awaits those who deny the truth! 14 O believers, when you meet unbelievers on the field of battle, do not turn your backs to them. 15 If anyone on that day turns his back to them in flight, except when maneuvering to fight, or to join another party, he shall be laden with the Anger of Allah and Gehenna shall be his refuge an evil arrival. 16 It was not you who killed them, but Allah slew them, neither was it you who threw at them. Allah threw at them in order that He confers on the believers a fair benefit. Indeed, Allah is Hearing, Knowing. 17 That, and also because Allah is He Who makes feeble the plans and stratagem of the Unbelievers. 18 O disbelievers! If you seek a judgement, then this judgement has come to you; and if you desist, it is better for you; and if you return to mischief, We will punish you again; and your populace will not benefit you, however large it may be – and besides this, Allah is with the Muslims. 19
