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 thou: the Holy Spirit hath brought it down from thy Lord with truth, that it may establish those who believe, and as a guidance and glad tidings unto the Muslims. 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 Indeed, those who do not believe in the verses of Allah - Allah will not guide them, and for them is a painful punishment. 104 It is those who believe not in the Signs of Allah, that forge falsehood: it is they who lie! 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 have given preference to this life over the life to come and God does not guide disbelieving people. 107 These are they on whose hearts and their hearing and their eyes Allah has set a seal, and these are the heedless ones. 108 Undoubtedly they in the Hereafter shall be the very losers. 109 ۞ Then, indeed your Lord, to those who emigrated after they had been compelled [to renounce their religion] and thereafter fought [for the cause of Allah] and were patient - indeed, your Lord, after that, is Forgiving and Merciful 110
