When He was causing slumber to overcome you as a security from Him, and sending down on you water from heaven, to purify you thereby, and to put away from you the defilement of Satan, and to strengthen your hearts, and to confirm your feet. 11 When thy Lord was revealing to the angels, 'I am with you; so confirm the believers. I shall cast into the unbelievers' hearts terror; so smite above the necks, and smite every finger of them!' 12 That, because they had made a breach with God and with His Messenger; and whosoever makes a breach with God and with His Messenger, surely God is terrible in retribution. 13 This is the torment, so taste it, and surely for the disbelievers is the torment of the Fire. 14 Believers, when you meet in battle those who deny the truth, never turn your backs on them: 15 (Whoever deserts the believers) will incur the wrath of God and will dwell in hell, a terrible dwelling. 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 Allah will surely weaken the guile of the unbelievers. 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
