He brought drowsiness upon you to give you His reassurance and sent down water from the sky upon you, so that He might thereby purify you and remove Satan's pollution from you, and make your hearts strong and your feet firm. 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 We will say to them, "Endure the torment (as a consequence of your evil deeds); the unbelievers deserve nothing better than (the torment) of fire." 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 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 You killed them not, but Allah killed them. And you (Muhammad SAW) threw not when you did throw but Allah threw, that He might test the believers by a fair trial from Him. Verily, Allah is All-Hearer, All-Knower. 17 Thus! And know that Allah weakeneth the contrivance of infidels. 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
