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 Verily those who believe not in the signs of Allah - Allah shall not guide them, and unto them shall be a torment afflictive. 104 It is only those who believe not in the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of Allah, who fabricate falsehood, and it is they who are liars. 105 Whosoever disbelieveth in Allah after his belief - save him who is constrained and his heart is at rest with the belief - but whosoever expandeth his breast to infidelity, upon them shall be wrath from Allah, and unto them shall be a torment mighty. 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 Those -- God has set a seal on their hearts, and their hearing, and their eyes, and those -- they are the heedless ones; 108 So it occurred that they are the losers in the Hereafter. 109 ۞ Yet surely your Lord, with respect to those who fly after they are persecuted, then they struggle hard and are patient, most surely your Lord after that is Forgiving, Merciful. 110
