And recall when Allah brought on you drowsiness, giving you a feeling of peace and security from Him, and He sent down rain upon you from the sky that He might cleanse you through it and take away from you the pollution of Satan and strengthen your hearts, and steady your feet through it. 11 And the Lord said to the angels: "I am with you; go and strengthen the faithful. I shall fill the hearts of infidels with terror. So smite them on their necks and every joint, (and incapacitate them)," 12 they have opposed God and His Messengers." For those who oppose God and His Messengers, God has prepared a severe retribution. 13 For you is this (punishment) to taste, for the infidels the torment of Hell. 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 Therefore take this, and (know that) Allah will weaken the scheme of the disbelievers. 18 You had asked for a judgement, so the judgement has come to you (In the form of victory for the faithful). So, if you desist it will be better for you. If you come back to it, We shall do the same, and your forces, however large, will not be of the least avail, for God is with those who believe. 19
