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: "Holy inspiration has brought it down from thy Sustainer by stages, setting forth the truth, so that it might give firmness unto those who have attained to faith, and provide guidance and a glad tiding unto all who have surrendered themselves to God." 102 And indeed We know that they (polytheists and pagans) say: "It is only a human being who teaches him (Muhammad SAW)." The tongue of the man they refer to is foreign, while this (the Quran) is a clear Arabic tongue. 103 God will not guide those who do not believe in His miracles. They will suffer a painful punishment. 104 Only they invent falsehood who believe not Allah's revelations, and (only) 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, because they have preferred the present life over the world to come, and that God guides not the people of the unbelievers. 107 God has sealed their hearts, ears and eyes and they are not aware of it. 108 On the Day of Judgment they will certainly be lost. 109 ۞ And yet, behold, thy Sustainer [grants His forgiveness] unto those who forsake the domain of evil after having succumbed to its temptation, and who thenceforth strive hard [in God's cause] and are patient in adversity: behold, after such [repentance] thy Sustainer is indeed much-forgiving, a dispenser of grace! 110
