(Remember) when He covered you with a slumber as a security from Him, and He caused water (rain) to descend on you from the sky, to clean you thereby and to remove from you the Rijz (whispering, evil-suggestions, etc.) of Shaitan (Satan), and to strengthen your hearts, and make your feet firm thereby. 11 When your Lord commanded the angels, saying, "I am with you, so make those who believe stand firm. I will instill fear in the hearts of those who deny the truth: so strike their necks and strike all their finger joints!" 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 your punishment, taste it then; and know that for those who deny the truth there is the punishment of the Fire. 14 O Ye who believe! whenever ye meet those who disbelieve marching slowly turn to them not your backs. 15 If anyone on that day turns his back to them in flight, except when maneuvering to fight, or to join another party, he shall be laden with the Anger of Allah and Gehenna shall be his refuge an evil arrival. 16 So you did not slay them, but it was Allah Who slew them, and you did not smite when you smote (the enemy), but it was Allah Who smote, and that He might confer upon the believers a good gift from Himself; surely Allah is Hearing, Knowing. 17 Allah will surely weaken the guile 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
