When He made the slumber fall upon you as a reassurance from him and sent down water from the sky upon you, that thereby He might purify you, and remove from you the fear of Satan, and make strong your hearts and firm (your) feet thereby. 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 is because they acted adversely to Allah and His Apostle; and whoever acts adversely to Allah and His Apostle-- then surely Allah is severe in requiting (evil). 13 That (is the award), so taste it, and (know) that for disbelievers is the torment of the Fire. 14 O ye who believe! when ye meet the Unbelievers in hostile array, never turn your backs to them. 15 If anyone on that day turns his back to them in flight, except when maneuvering to fight, or to join another party, he shall be laden with the Anger of Allah and Gehenna shall be his refuge an evil arrival. 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 His manner of dealing with you. As for the unbelievers, Allah will surely undermine their designs. 18 You had asked for a judgement, so the judgement has come to you (In the form of victory for the faithful). So, if you desist it will be better for you. If you come back to it, We shall do the same, and your forces, however large, will not be of the least avail, for God is with those who believe. 19
