When We substitute one revelation for another,- and Allah knows best what He reveals (in stages),- they say, "Thou art but a forger": but most of them understand not. 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 Indeed, We know what they say, "It is only a human being who imparts [all] this to him!" But the tongue of him to whom they point is foreign, whereas this is plain Arabic speech. 103 Verily, as for those who will not believe in God's messages, God does not guide them aright; and grievous suffering will be their lot [in the life to come]. 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 Whosoever disbelieveth in Allah after his belief - save him who is constrained and his heart is at rest with the belief - but whosoever expandeth his breast to infidelity, upon them shall be wrath from Allah, and unto them shall be a torment mighty. 106 This is because they love this world's life more than the hereafter, and because Allah does not guide the unbelieving people. 107 These are they on whose hearts and their hearing and their eyes Allah has set a seal, and these are the heedless ones. 108 without a doubt, in the world to come they will 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
