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 Lo! Thy Sustainer inspired the angels [to convey this His message to the believers]: "I am with you!" [And He commanded the angels:] "And give firmness unto those who have attained to faith [with these words from Me]: 'I shall cast terror into the hearts of those who are bent on denying the truth; strike, then, their necks, [O believers,] and strike off every one of their finger-tips!" 12 This is because they defied and disobeyed Allah and His Messenger. And whoever defies and disobeys Allah and His Messenger, then verily, Allah is Severe in punishment. 13 This! taste it then, and know that for the infidels is the torment of the Fire. 14 Believers, when you encounter unbelievers on the march do not turn your backs to them in flight. 15 Whoso turns his back that day to them, unless withdrawing to fight again or removing to join another host, he is laden with the burden of God's anger, and his refuge is Gehenna -- an evil homecoming! 16 You did not slay them, but God slew them; and when thou threwest, it was not thyself that threw, but God threw, and that He might confer on the believers a fair benefit; surely God is All-hearing, All-knowing. 17 Thus! And know that Allah weakeneth the contrivance of infidels. 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
