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 thou: the Holy Spirit hath brought it down from thy Lord with truth, that it may establish those who believe, and as a guidance and glad tidings unto the Muslims. 102 And We know very well that they say, 'Only a mortal is teaching him.' The speech of him at whom they hint is barbarous; and this is speech Arabic, manifest. 103 Indeed, those who do not believe in the verses of Allah - Allah will not guide them, and for them is a painful punishment. 104 It is those who believe not in the Signs of Allah, that forge falsehood: it is they who lie! 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 These are they on whose hearts and their hearing and their eyes Allah has set a seal, and these are the heedless ones. 108 Assuredly, it is they, in the Hereafter, who will 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
