When We substitute one revelation for another,- and Allah knows best what He reveals (in stages),- they say, "Thou art but a forger": but most of them understand not. 101 Say: 'The Holy Spirit sent it down from thy Lord in truth, and to confirm those who believe, and to be a guidance and good tidings to those who surrender.' 102 We know indeed that they say, "It is a man that teaches him." The tongue of him they wickedly point to is notably foreign, while this is Arabic, pure and clear. 103 Those that believe not in the signs of God, God will not guide; there awaits them a painful chastisement. 104 None forge lies except those who disbelieve the verses of Allah those, they are the liars. 105 Whosoever disbelieves in Allah after believing except he who is forced while his heart remains in his belief but he who opens his chest for disbelief, shall receive the Anger of Allah and for such awaits a mighty punishment. 106 This is because they prefer the life of this world to the Hereafter and because God does not guide those who deny the truth. 107 These are the ones upon whose hearts and hearing and sight God has set a seal. It is they who are heedless, 108 Assuredly in the Hereafter they are the losers. 109 ۞ And surely your Lord will be Most Forgiving and Most Merciful towards those who left their homes after they were persecuted, and who thereafter struggled hard and remained constant. 110
