When We exchange a verse for another and Allah knows best what He is sending down they say: 'You are but a forger' No, most of them do not know. 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 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 Verily! Those who believe not in the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of Allah, Allah will not guide them and theirs will be a painful torment. 104 Only they invent falsehood who believe not Allah's revelations, and (only) they are the liars. 105 Whosoever denies having once believed -- unless he is forced to do so while his heart enjoys the peace of faith -- and opens his mind to disbelief will suffer the wrath of God. Their punishment will be great, 106 This is because they prefer the life of this world to the Hereafter and because God does not guide those who deny the truth. 107 They are those upon whose hearts, hearing (ears) and sight (eyes) Allah has set a seal. And they are the heedless! 108 Truly it is they, they who in the life to come shall be the losers! 109 ۞ Then indeed your Lord? to those who emigrated, after they were persecuted, and then strove and were patient, surely, your Lord is thereafter Forgiving, the Most Merciful. 110
