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 assuredly We know that they say: it is only a human being who teacheth him. The speech of him unto whom they incline is foreign while this is Arabic speech plain. 103 Those that believe not in the signs of God, God will not guide; there awaits them a painful chastisement. 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 This because they love the life of this world better than the Hereafter: and Allah will not guide those who reject Faith. 107 These are they upon whose hearts and hearing and sight Allah hath set a seal; and these! they are the negligent. 108 Without doubt, in the Hereafter they will perish. 109 ۞ Then indeed your Lord – for those who migrated after they had been oppressed, and then fought and remained patient – indeed your Lord is then, surely, Oft Forgiving, Most Merciful. 110
