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 And assuredly We know that they say: it is only a human being who teacheth him. The speech of him unto whom they incline is foreign while this is Arabic speech plain. 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 (It is not the Prophet who invents lies), it is rather those who do not believe in the signs of Allah who invent lies. They are liars. 105 Whoso disbelieves in God, after he has believed -- excepting him who has been compelled, and his heart is still at rest in his belief -- but whosoever's breast is expanded in unbelief, upon them shall rest anger from God, and there awaits them a mighty chastisement; 106 This is because they have given preference to this life over the life to come and God does not guide disbelieving people. 107 They are the ones upon whose hearts and hearing and eyes Allah has set a seal. They are utterly steeped in heedlessness. 108 No doubt that in the hereafter they will be the losers. 109 ۞ Then, verily, thy Lord unto those who have emigrated after they had been tempted and have thereafter striven hard and endured, verily thy Lord thereafter is Forgiving, Merciful. 110
