(Remember) when He covered you with a slumber as a security from Him, and He caused water (rain) to descend on you from the sky, to clean you thereby and to remove from you the Rijz (whispering, evil-suggestions, etc.) of Shaitan (Satan), and to strengthen your hearts, and make your feet firm thereby. 11 And recall when your Lord inspired the angels: 'I am certainly with you. So make firm the feet of those who believe. I will cast terror into the hearts of those who disbelieve. So strike at their necks and strike at every pore and tip. 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 This-- taste it, and (know) that for the unbelievers is the chastisement of fire. 14 O believers, when you encounter the unbelievers marching to battle, turn not your backs to them. 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 Wherefore ye slew them not, but Allah slew them, and thou threwest not, when thou threwest, but Allah threw, in order that He might prove the believers with a goodly proving from Him. Verily Allah is Hearing, Knowing. 17 Thus! And know that Allah weakeneth the contrivance of infidels. 18 If you were seeking a victory, victory has now come to you. If you desist, it will be better for you. If you resume We will return, and even if your forces are numerous, they shall not help you at all. And Allah is with the believers. 19
