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 (O Muhammad SAW) Ruh-ul-Qudus [Jibrael (Gabriel)] has brought it (the Quran) down from your Lord with truth, that it may make firm and strengthen (the Faith of) those who believe and as a guidance and glad tidings to those who have submitted (to Allah as 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 Those who do not believe in the miracles of God invent lies and they are liars. 105 Whosoever disbelieveth in Allah after his belief - save him who is constrained and his heart is at rest with the belief - but whosoever expandeth his breast to infidelity, upon them shall be wrath from Allah, and unto them shall be a torment mighty. 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 They whose hearts and whose hearing and whose sight God has sealed - it is they, they who are heedless! 108 They will surely be losers in the life to come, 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
