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 You say: "It has been sent by divine grace from your Lord with truth to strengthen those who believe, and as guidance and good news for those who have submitted (to God)." 102 And We certainly know that they say, "It is only a human being who teaches the Prophet." The tongue of the one they refer to is foreign, and this Qur'an is [in] a clear Arabic language. 103 Lo! those who disbelieve the revelations of Allah, Allah guideth them not and theirs will be a painful doom. 104 Those who do not believe in the miracles of God invent lies and they are liars. 105 As for one who denies God after he has believed, with the exception of one who is forced to do it, while his heart rests securely in faith, but one who opens his heart to a denial of truth shall incur the wrath of God; such as these will have a terrible punishment. 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 without a doubt, in the world to come 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
