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, "The Holy Spirit has brought it down as truth from your Lord, so that He may strengthen those who believe, and also as guidance and as good tidings for those who submit." 102 And indeed We know that they (polytheists and pagans) say: "It is only a human being who teaches him (Muhammad SAW)." The tongue of the man they refer to is foreign, while this (the Quran) is a clear Arabic tongue. 103 Those who disbelieve in the verses of Allah, Allah does not guide them for them is a painful punishment. 104 Only they forge the lie who do not believe in Allah's communications, and these are the liars. 105 He who disbelieves in Allah after his having believed, not he who is compelled while his heart is at rest on account of faith, but he who opens (his) breast to disbelief-- on these is the wrath of Allah, and they shall have a grievous chastisement. 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 upon whose hearts and hearing and sight Allah hath set a seal; and these! they are the negligent. 108 and in the life to come, they will surely 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
