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 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 indeed We know that they say, “This Qur’an is being taught by some other man”; the one they refer to speaks a foreign language, whereas this is clear Arabic! 103 Those who believe not in the Signs of Allah,- Allah will not guide them, and theirs will be a grievous Penalty. 104 Only they forge the lie who do not believe in Allah's communications, and these 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 This is because they prefer the life of this world to the Hereafter and because God does not guide those who deny the truth. 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 Without doubt, in the Hereafter they will perish. 109 ۞ Then, verily, thy Lord unto those who have emigrated after they had been tempted and have thereafter striven hard and endured, verily thy Lord thereafter is Forgiving, Merciful. 110
