A blanketing sleep came over you as a (measure of) security from Him, and He sent down rain from the skies to cleanse you, and to remove the plague of Satan, and to strengthen your hearts and steady your steps. 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, because they have cut themselves off from God and His Apostle: and as for him who cuts himself off from God and His Apostle - verily, God is severe in retribution. 13 That is your punishment, taste it then; and know that for those who deny the truth there is the punishment of the Fire. 14 O believers, when you encounter the unbelievers marching to battle, turn not your backs to them. 15 And whoever turns his back to them on such a day, unless swerving [as a strategy] for war or joining [another] company, has certainly returned with anger [upon him] from Allah, and his refuge is Hell - and wretched is the destination. 16 You did not kill them; it was God who killed them; and when you [Prophet] threw [sand] at them it was not you, but God who threw it so that He might confer on the believers a great favour from Himself. Surely, God is all hearing, all-knowing, 17 This (is the fact) and surely, Allah weakens the deceitful plots of the disbelievers. 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
