And now that We replace one message by another - since God is fully aware of what He bestows from on high, step by step - they [who deny the truth] are wont to say: "Thou but inventest it!" Nay, but most of them do not understand it! 101 Tell them: "It is the spirit of holiness that has brought it down, by stages, from your Lord so that it might bring firmness to those who believe, and guidance to the Right Way, and give glad tidings of felicity and success to those who submit to Allah." 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 signs of Allah - Allah shall not guide them, and unto them shall be a torment afflictive. 104 It is only those who believe not in the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of Allah, who fabricate falsehood, and it is they who are liars. 105 Whoever disbelieves in Allah after his belief... except for one who is forced [to renounce his religion] while his heart is secure in faith. But those who [willingly] open their breasts to disbelief, upon them is wrath from Allah, and for them is a great punishment; 106 That is because they loved the life of the world above the Hereafter, and because Allah guideth not an infidel people. 107 God has sealed their hearts, ears and eyes and they are not aware of it. 108 In the Everlasting Life, they shall assuredly 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
