Recall what time He caused slumber to cover you as a security from Himself, and He sent down rain upon you from heaven that he might cleanse you thereby and take away from you the pollution of the Satan, and that he might gird up your hearts and make your feet firm thereby. 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 For they had opposed God and His Apostle; but whosoever opposes God and his Apostle (should know) that God is severe in retribution. 13 'That for you, so taste it, the punishment of the Fire is for the unbelievers' 14 O People who Believe! When you confront a large army of disbelievers in battle, do not turn your backs to them. 15 For any one who turns his back on that day, except to manoeuvre or rally to his side, will bring the wrath of God on himself, and have Hell as abode; and what an evil destination! 16 And you did not kill them, but it was Allah who killed them. And you threw not, [O Muhammad], when you threw, but it was Allah who threw that He might test the believers with a good test. Indeed, Allah is Hearing and Knowing. 17 This (is the fact) and surely, Allah weakens the deceitful plots of the disbelievers. 18 (Tell the unbelievers:) 'If you have sought a judgement, then surely a judgement has come to you. And if you desist from disobedience, it is all the better for you. But if you revert to your mischief, We will again chastise you; and your host, howsoever numerous, will never be of any avail to you. Know well, Allah is with the believers.' 19
