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 who disbelieve in the verses of Allah, Allah does not guide them for them is a painful punishment. 104 It is only those who believe not in the signs of Allah who fabricate lie, and those! they are the liars. 105 Whoso disbelieveth in Allah after his belief - save him who is forced thereto and whose heart is still content with the Faith - but whoso findeth ease in disbelief: On them is wrath from Allah. Theirs will be an awful doom. 106 This is because the worldly life was dearer to them than the Hereafter; and because Allah does not guide such disbelieving people. 107 Those are they whose hearts, ears, and eyes Allah has sealed up, and they take no heed. 108 In the Everlasting Life, they shall assuredly be the losers. 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
