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 has revealed it from your Lord with the truth, that it may establish those who believe and as a guidance and good news for those who submit. 102 We know that they say a mere mortal has taught it (the Quran) to him (Muhammad). The language of the person whom they think has taught it to him is not Arabic. This (the Quran) is in illustrious Arabic. 103 Verily, as for those who will not believe in God's messages, God does not guide them aright; and grievous suffering will be their lot [in the life to come]. 104 None forge lies except those who disbelieve the verses of Allah 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 all this, because they hold this world's life in greater esteem than the life to come, and because God does not bestow His guidance upon people who deny the truth. 107 They whose hearts and whose hearing and whose sight God has sealed - it is they, they who are heedless! 108 Undoubtedly they in the Hereafter shall be the very losers. 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
