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 has revealed it from your Lord with the truth, that it may establish those who believe and as a guidance and good news for those who submit. 102 Indeed, We know what they say, "It is only a human being who imparts [all] this to him!" But the tongue of him to whom they point is foreign, whereas this is plain Arabic speech. 103 Those that believe not in the signs of God, God will not guide; there awaits them a painful chastisement. 104 (It is not the Prophet who invents lies), it is rather those who do not believe in the signs of Allah who invent lies. They are liars. 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 love the life of this world more than the Hereafter; and Allah does not guide those who are ungrateful to Allah for His favours. 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, verily, thy Lord unto those who have emigrated after they had been tempted and have thereafter striven hard and endured, verily thy Lord thereafter is Forgiving, Merciful. 110
