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 We know well that they say: Only a man teacheth him. The speech of him at whom they falsely hint is outlandish, and this is clear Arabic speech. 103 God will not guide those who do not believe in His miracles. They will suffer a painful punishment. 104 None forge lies except those who disbelieve the verses of Allah 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 This is because they have given preference to this life over the life to come and God does not guide disbelieving people. 107 Those -- God has set a seal on their hearts, and their hearing, and their eyes, and those -- they are the heedless ones; 108 No doubt they shall be losers in the Hereafter. 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
