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 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 This is because they opposed Allah and His Noble Messenger; and whoever opposes Allah and His Noble Messenger – then indeed Allah’s punishment is severe. 13 "That [is yours], so taste it." And indeed for the disbelievers is the punishment of the Fire. 14 Believers, do not retreat when facing the marching army of the unbelievers, for no believer will turn back at that time except for strategic reasons or to join another band. 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 So you did not slay them, but it was Allah Who slew them, and you did not smite when you smote (the enemy), but it was Allah Who smote, and that He might confer upon the believers a good gift from Himself; surely Allah is Hearing, Knowing. 17 Thus! And know that Allah weakeneth the contrivance of infidels. 18 (O disbelievers) if you ask for a judgement, now has the judgement come unto you and if you cease (to do wrong), it will be better for you, and if you return (to the attack), so shall We return, and your forces will be of no avail to you, however numerous it be, and verily, Allah is with the believers. 19
