And when We exchange a verse in the place of another verse and God knows very well what He is sending down -- they say, 'Thou art a mere forger!' Nay, but the most of them have no knowledge. 101 Say thou: the Holy Spirit hath brought it down from thy Lord with truth, that it may establish those who believe, and as a guidance and glad tidings unto the Muslims. 102 We know that they say a mere mortal has taught it (the Quran) to him (Muhammad). The language of the person whom they think has taught it to him is not Arabic. This (the Quran) is in illustrious Arabic. 103 Those who disbelieve in the verses of Allah, Allah does not guide them for them is a painful punishment. 104 Only they invent falsehood who believe not Allah's revelations, and (only) they are the liars. 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 loved the life of the world above the Hereafter, and because Allah guideth not an infidel people. 107 These are they on whose hearts and their hearing and their eyes Allah has set a seal, and these are the heedless ones. 108 They will surely be losers in the life to come, 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
