When God replaces one revelation with another, He knows best what to reveal. But they say, "(Muhammad), you have falsely invented it." Most people are ignorant. 101 Say, the Holy Spirit has brought the revelation from thy Lord in Truth, in order to strengthen those who believe, and as a Guide and Glad Tidings to 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 Lo! those who disbelieve the revelations of Allah, Allah guideth them not and theirs will be a painful doom. 104 It is only those who believe not in the signs of Allah who fabricate lie, and those! they are the liars. 105 As for anyone who denies God after having once attained to faith - and this, to be sure, does not apply to one who does it under duress, the while his heart remains true to his faith, but [only, to] him who willingly opens up his heart to a denial of the truth: upon all such [falls] God's condemnation, and tremendous suffering awaits them: 106 This because they love the life of this world better than the Hereafter: and Allah will not guide those who reject Faith. 107 They are the ones whose hearts and ears and eyes have been sealed by God; and these are the heedless. 108 Assuredly, it is they, in the Hereafter, who 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
