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 Your Lord inspired the angels saying, "I am with you. Encourage the believers. I shall cast terror into the hearts of the unbelievers and you will strike their heads and limbs; 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 [is yours], so taste it." And indeed for the disbelievers is the punishment of the Fire. 14 Believers, when you encounter unbelievers on the march do not turn your backs to them in flight. 15 If any do turn his back to them on such a day - unless it be in a stratagem of war, or to retreat to a troop (of his own)- he draws on himself the wrath of Allah, and his abode is Hell,- an evil refuge (indeed)! 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 Therefore take this, and (know that) Allah will weaken the scheme of the disbelievers. 18 If victory you are seeking, victory has already come upon you; and if you give over, it is better for you. But if you return, We shall return, and your host will avail you nothing though it be numerous; and that God is with the believers. 19
