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 When your Lord revealed to the angels: I am with you, therefore make firm those who believe. I will cast terror into the hearts of those who disbelieve. Therefore strike off their heads and strike off every fingertip of them. 12 This is because they defied Allah and His Messenger. Whoever defies Allah and His Messenger must know that Allah is severe in punishment. 13 This! taste it then, and know that for the infidels is the torment of the Fire. 14 O believers, when you meet unbelievers on the field of battle, do not turn your backs to them. 15 for, whoever on that day turns his back on them - unless it be in a battle manoeuvre or in an endeavour to join another troop [of the believers] - shall indeed have earned the burden of God's condemnation, and his goal shall be hell: and how vile a journey's end! 16 It was not you who killed them, but God did so. You did not throw what you threw, (sand into the eyes of the enemy at Badr), but God, to bring out the best in the faithful by doing them a favour of His own. God is all-hearing and all-knowing. 17 This [was God's purpose] - and also [to show] that God renders vain the artful schemes of those who deny the truth. 18 (O disbelievers) if you ask for a judgement, now has the judgement come unto you and if you cease (to do wrong), it will be better for you, and if you return (to the attack), so shall We return, and your forces will be of no avail to you, however numerous it be, and verily, Allah is with the believers. 19
