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 Tell them: "It is the spirit of holiness that has brought it down, by stages, from your Lord so that it might bring firmness to those who believe, and guidance to the Right Way, and give glad tidings of felicity and success to those who submit to Allah." 102 And indeed We know that they say, “This Qur’an is being taught by some other man”; the one they refer to speaks a foreign language, whereas this is clear Arabic! 103 Those who do not believe in the words of God are verily not guided by God. For them is severe punishment. 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 Except for those who were forced to engage in infidelity to Allah after believing the while their hearts remained firmly convinced of their belief, the ones whose hearts willingly embraced disbelief shall incur Allah's wrath and a mighty chastisement lies in store for them. 106 That is because they preferred the worldly life over the Hereafter and that Allah does not guide the disbelieving people. 107 These are the ones upon whose hearts and hearing and sight God has set a seal. It is they who are heedless, 108 No doubt they shall be losers in the Hereafter. 109 ۞ But (to) those who were victimised and left their homes and then fought and endured patiently, your Lord will surely be forgiving and kind. 110
