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 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 disbelieve in the verses of Allah, Allah does not guide them for them is a painful punishment. 104 Those who do not believe in the miracles of God invent lies and they are liars. 105 Whosoever denies having once believed -- unless he is forced to do so while his heart enjoys the peace of faith -- and opens his mind to disbelief will suffer the wrath of God. Their punishment will be great, 106 That is because they preferred the worldly life over the Hereafter and that Allah does not guide the disbelieving people. 107 They are those upon whose hearts, hearing (ears) and sight (eyes) Allah has set a seal. And they are the heedless! 108 and in the life to come, they will surely be the losers. 109 ۞ Then lo! thy Lord - for those who became fugitives after they had been persecuted, and then fought and were steadfast - lo! thy Lord afterward is (for them) indeed Forgiving, Merciful. 110
