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 sent it down from thy Lord in truth, and to confirm those who believe, and to be a guidance and good tidings to those who surrender.' 102 And We know well that they say: Only a man teacheth him. The speech of him at whom they falsely hint is outlandish, and this is clear Arabic speech. 103 Surely Allah will not enable those who do not believe in the signs of Allah to be directed to the Right Way, and a painful chastisement awaits them. 104 It is only those who believe not in the signs of Allah who fabricate lie, and those! they are the liars. 105 Whosoever disbelieves in Allah after believing except he who is forced while his heart remains in his belief but he who opens his chest for disbelief, shall receive the Anger of Allah and for such awaits a mighty punishment. 106 That is because they have chosen the life of the world rather than the Hereafter, and because Allah guideth not the disbelieving folk. 107 These are they upon whose hearts and hearing and sight Allah hath set a seal; and these! they are the negligent. 108 No doubt they shall be losers in the Hereafter. 109 ۞ Then, indeed your Lord, to those who emigrated after they had been compelled [to renounce their religion] and thereafter fought [for the cause of Allah] and were patient - indeed, your Lord, after that, is Forgiving and Merciful 110
