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 when Allah revealed to the angels, saying: 'I shall be with you. Give courage to the believers. I shall cast terror into the hearts of the unbelievers. Strike them above the necks, smite their finger tips' 12 That is because they opposed Allah and His messenger. Whoso opposeth Allah and His messenger, (for him) lo! Allah is severe in punishment. 13 That for you; therefore taste it; and that the chastisement of the Fire is for the unbelievers. 14 Believers, when you meet in battle those who deny the truth, never turn your backs on them: 15 And whoever shall turn his back to them on that day-- unless he turn aside for the sake of fighting or withdraws to a company-- then he, indeed, becomes deserving of Allah's wrath, and his abode is hell; and an evil destination shall it be. 16 And you did not kill them, but it was Allah who killed them. And you threw not, [O Muhammad], when you threw, but it was Allah who threw that He might test the believers with a good test. Indeed, Allah is Hearing and Knowing. 17 Therefore take this, and (know that) Allah will weaken the scheme of the disbelievers. 18 If ye besought a judgement then surely a judgement hath come unto you. And if ye desist it will be better for you; and if ye return We will return; and your host shall avail you not, although numerous it be; and know that verily Allah is with the believers. 19
