Whenever We replace one verse by another verse - and Allah knows what He should reveal - they are wont to say: "You are nothing but a fabricator (who has invented the Qur'an)." The fact is that most of them are ignorant of the Truth. 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 We certainly know that they say, "It is only a human being who teaches the Prophet." The tongue of the one they refer to is foreign, and this Qur'an is [in] a clear Arabic language. 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 those who believe not in the Signs of Allah, that forge falsehood: it is they who lie! 105 As for anyone who denies God after having once attained to faith - and this, to be sure, does not apply to one who does it under duress, the while his heart remains true to his faith, but [only, to] him who willingly opens up his heart to a denial of the truth: upon all such [falls] God's condemnation, and tremendous suffering awaits them: 106 That is because they preferred the worldly life over the Hereafter and that Allah does not guide the disbelieving people. 107 These are the ones upon whose hearts and hearing and sight God has set a seal. It is they who are heedless, 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
