When We substitute one revelation for another, and God knows best what He reveals, they say, "You are but a fabricator." Indeed, most of them have no knowledge. 101 Say, the Holy Spirit has brought the revelation from thy Lord in Truth, in order to strengthen those who believe, and as a Guide and Glad Tidings to Muslims. 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 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 He who disbelieves in Allah after his having believed, not he who is compelled while his heart is at rest on account of faith, but he who opens (his) breast to disbelief-- on these is the wrath of Allah, and they shall have a grievous chastisement. 106 That is because they loved this present life above the Everlasting Life. Allah does not guide the unbelievers. 107 Those are they whose hearts, ears, and eyes Allah has sealed up, and they take no heed. 108 Assuredly, it is they, in the Hereafter, who will 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
