When We substitute one revelation for another,- and Allah knows best what He reveals (in stages),- they say, "Thou art but a forger": but most of them understand not. 101 (Muhammad), say, "The Holy Spirit has brought the Quran from your Lord to you in all truth to strengthen the faith of the believers and to be a guide and glad news for 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 Those who do not believe in the words of God are verily not guided by God. For them is severe punishment. 104 It is but they who will not believe in God's messages that invent this falsehood; and it is they, they who are lying! 105 Whoso disbelieves in God, after he has believed -- excepting him who has been compelled, and his heart is still at rest in his belief -- but whosoever's breast is expanded in unbelief, upon them shall rest anger from God, and there awaits them a mighty chastisement; 106 That is because they have chosen the life of the world rather than the Hereafter, and because Allah guideth not the disbelieving folk. 107 They are the ones whose hearts and ears and eyes have been sealed by God; and these are the 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
