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 Say (O Muhammad SAW) Ruh-ul-Qudus [Jibrael (Gabriel)] has brought it (the Quran) down from your Lord with truth, that it may make firm and strengthen (the Faith of) those who believe and as a guidance and glad tidings to those who have submitted (to Allah as Muslims). 102 We know very well that they say: 'A mortal teaches him' The tongue of him at whom they hint is a nonArab; and this is a clear Arabic tongue. 103 (As for) those who do not believe in Allah's communications, surely Allah will not guide them, and they shall have a painful punishment. 104 It is but they who will not believe in God's messages that invent this falsehood; and it is they, they who are lying! 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 That is because they loved the life of the world above the Hereafter, and because Allah guideth not an infidel people. 107 Those are they whose hearts, ears, and eyes Allah has sealed up, and they take no heed. 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
