When He made the slumber overcome you, so it was as a peacefulness from Him, and sent down water from the sky upon you to purify you with it, and to remove the impurity of Satan from you, and to give your hearts fortitude and firmly establish your feet with it. 11 When your Lord revealed to the angels: I am with you, therefore make firm those who believe. I will cast terror into the hearts of those who disbelieve. Therefore strike off their heads and strike off every fingertip of them. 12 This is because they had made a breach with Allah and His Messenger. He who makes a breach with Allah and His Messenger indeed, Allah is stern in retribution. 13 That for you; therefore taste it; and that the chastisement of the Fire is for the unbelievers. 14 O YOU who have attained to faith! When you meet in battle those who are bent on denying the truth, advancing in great force, do not 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 slay them, but God slew them; and when thou threwest, it was not thyself that threw, but God threw, and that He might confer on the believers a fair benefit; surely God is All-hearing, All-knowing. 17 This, and that Allah is the weakener of the struggle of the unbelievers. 18 If you demanded a judgment, the judgment has then indeed come to you; and if you desist, it will be better for you; and if you turn back (to fight), We (too) shall turn back, and your forces shall avail you nothing, though they may be many, and (know) that Allah is with the believers. 19
