He brought drowsiness upon you to give you His reassurance and sent down water from the sky upon you, so that He might thereby purify you and remove Satan's pollution from you, and make your hearts strong and your feet firm. 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 opposed Allah and His Noble Messenger; and whoever opposes Allah and His Noble Messenger – then indeed Allah’s punishment is severe. 13 "That [is yours], so taste it." And indeed for the disbelievers is the punishment of the Fire. 14 Believers, do not retreat when facing the marching army of the unbelievers, for no believer will turn back at that time except for strategic reasons or to join another band. 15 And on that day whoever turns his back to them, except for a battle strategy or to join one’s own company, has then turned towards Allah’s wrath, and his destination is hell; and what an evil place of return! 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 This is how God causes the (evil) plans of the unbelievers to fail. 18 If ye besought a judgement then surely a judgement hath come unto you. And if ye desist it will be better for you; and if ye return We will return; and your host shall avail you not, although numerous it be; and know that verily Allah is with the believers. 19
