[Remember] when He overwhelmed you with drowsiness [giving] security from Him and sent down upon you from the sky, rain by which to purify you and remove from you the evil [suggestions] of Satan and to make steadfast your hearts and plant firmly thereby your feet. 11 (Remember) when your Lord inspired the angels, "Verily, I am with you, so keep firm those who have believed. I will cast terror into the hearts of those who have disbelieved, so strike them over the necks, and smite over all their fingers and toes." 12 This, because they have resisted Allah and His apostle; and whosoever resisteth Allah and His apostle, then verily Allah is severe in retribution. 13 Thus (will it be said): "Taste ye then of the (punishment): for those who resist Allah, is the penalty of the Fire." 14 O believers, when you encounter the unbelievers marching to battle, turn not your backs to them. 15 For he who turns his back on them on such ar occasion - except that it be for tactical reasons, or turning to join another company - he shall incur the wrath of Allah and Hell shall be his abode. It is an evil destination. 16 And yet, [O believers,] it was not you who slew the enemy, but it was God who slew them; and it was not thou who cast [terror into them, O Prophet,] when thou didst cast it, but it was God who cast it: and [He did all this] in order that He might test the believers by a goodly test of His Own ordaining. Verily, God is all-hearing, all-knowing! 17 Therefore take this, and (know that) Allah will weaken the scheme of the disbelievers. 18 (O Qureysh!) If ye sought a judgment, now hath the judgment come unto you. And if ye cease (from persecuting the believers) it will be better for you, but if ye return (to the attack) We also shall return. And your host will avail you naught, however numerous it be, and (know) that Allah is with the believers (in His Guidance). 19
