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 Yet We know what they say: "It is only a man who instructs him." The speech of the man they imply is obscure while this is clear Arabic. 103 Verily, as for those who will not believe in God's messages, God does not guide them aright; and grievous suffering will be their lot [in the life to come]. 104 It is but they who will not believe in God's messages that invent this falsehood; and it is they, they who are lying! 105 As for one who denies God after he has believed, with the exception of one who is forced to do it, while his heart rests securely in faith, but one who opens his heart to a denial of truth shall incur the wrath of God; such as these will have a terrible punishment. 106 For they loved the life of this world more than the life to come; and God does not guide those who do not believe. 107 Those are they whose hearts, ears, and eyes Allah has sealed up, and they take no heed. 108 They will surely be losers in the life to come, 109 ۞ Then, surely thy Lord -- unto those who have emigrated after persecution, then struggled and were patient -- surely thy Lord thereafter is All-forgiving, All-compassionate. 110
