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 hath delivered it from thy Lord with truth, that it may confirm (the faith of) those who believe, and as guidance and good tidings for those who have surrendered (to Allah). 102 And indeed We know that they say, “This Qur’an is being taught by some other man”; the one they refer to speaks a foreign language, whereas this is clear Arabic! 103 Those who disbelieve in the verses of Allah, Allah does not guide them for them is a painful punishment. 104 It is only those who believe not in the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of Allah, who fabricate falsehood, and it is they who are liars. 105 No one verbally denounces his faith in God - unless he is forced - but his heart is confident about his faith. But those whose breasts have become open to disbelief will be subject to the wrath of God and will suffer a great torment. 106 That is because they loved this present life above the Everlasting Life. Allah does not guide the unbelievers. 107 Those -- God has set a seal on their hearts, and their hearing, and their eyes, and those -- they are the heedless ones; 108 Truly it is they, they who in the life to come shall 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
