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], "The Pure Spirit has brought it down from your Lord in truth to make firm those who believe and as guidance and good tidings to 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 God will not guide those who will not believe in the signs of God; and theirs will be 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 Any one who, after accepting faith in Allah, utters Unbelief,- except under compulsion, his heart remaining firm in Faith - but such as open their breast to Unbelief, on them is Wrath from Allah, and theirs will be a dreadful Penalty. 106 that, because they have preferred the present life over the world to come, and that God guides not the people of the unbelievers. 107 Those -- God has set a seal on their hearts, and their hearing, and their eyes, and those -- they are the heedless ones; 108 Truly it is they, they who in the life to come shall be the losers! 109 ۞ Surely, your Lord will be forgiving and merciful towards those who migrated after persecution and strove hard for the cause of God and remained steadfast. 110
