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 hath delivered it from thy Lord with truth, that it may confirm (the faith of) those who believe, and as guidance and good tidings for those who have surrendered (to Allah). 102 And indeed We know that they (polytheists and pagans) say: "It is only a human being who teaches him (Muhammad SAW)." The tongue of the man they refer to is foreign, while this (the Quran) is a clear Arabic tongue. 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 None forge lies except those who disbelieve the verses of Allah those, they are the liars. 105 As for one who denies God after he has believed, with the exception of one who is forced to do it, while his heart rests securely in faith, but one who opens his heart to a denial of truth shall incur the wrath of God; such as these will have a terrible punishment. 106 That is because they loved and preferred the life of this world over that of the Hereafter. And Allah guides not the people who disbelieve. 107 These are the ones upon whose hearts and hearing and sight God has set a seal. It is they who are heedless, 108 without a doubt, in the world to come they will be the losers. 109 ۞ But verily thy Lord,- to those who leave their homes after trials and persecutions,- and who thereafter strive and fight for the faith and patiently persevere,- Thy Lord, after all this is oft-forgiving, Most Merciful. 110
