Recall what time He caused slumber to cover you as a security from Himself, and He sent down rain upon you from heaven that he might cleanse you thereby and take away from you the pollution of the Satan, and that he might gird up your hearts and make your feet firm thereby. 11 (Remember) when your Lord inspired the angels, "Verily, I am with you, so keep firm those who have believed. I will cast terror into the hearts of those who have disbelieved, so strike them over the necks, and smite over all their fingers and toes." 12 This is because they defied Allah and His Messenger. Whoever defies Allah and His Messenger must know that Allah is severe in punishment. 13 This is the torment, so taste it, and surely for the disbelievers is the torment of the Fire. 14 O People who Believe! When you confront a large army of disbelievers in battle, do not turn 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 So the fact is that it was not you, but it was Allah Who killed them; and it was not you when you threw [sand at them], but it was Allah Who threw it, (and the believers were employed for the task) that He might cause the believers to successfully pass through this test. Allah is All-Hearing, All-Knowing. 17 This is His manner of dealing with you. As for the unbelievers, Allah will surely undermine their designs. 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
