And when We substitute a verse in place of a verse - and Allah is most knowing of what He sends down - they say, "You, [O Muhammad], are but an inventor [of lies]." But most of them do not know. 101 Say: 'The Holy Spirit (Gabriel) brought it down from your Lord in truth to confirm those who believe, and to give guidance and glad tidings to those who surrender' 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 believe not in the Signs of Allah,- Allah will not guide them, and theirs will be a grievous Penalty. 104 Only those fabricate lies concerning God who do not believe in the signs of God, and these 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 is because they loved this present life above the Everlasting Life. Allah does not guide the unbelievers. 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 that in the hereafter they will be the losers. 109 ۞ Then lo! thy Lord - for those who became fugitives after they had been persecuted, and then fought and were steadfast - lo! thy Lord afterward is (for them) indeed Forgiving, Merciful. 110
