And when We change (one) communication for (another) communication, and Allah knows best what He reveals, they say: You are only a forger. Nay, most of them do not know. 101 Tell them: "It is the spirit of holiness that has brought it down, by stages, from your Lord so that it might bring firmness to those who believe, and guidance to the Right Way, and give glad tidings of felicity and success to those who submit to Allah." 102 We know that they say a mere mortal has taught it (the Quran) to him (Muhammad). The language of the person whom they think has taught it to him is not Arabic. This (the Quran) is in illustrious Arabic. 103 Those who disbelieve in the signs of Allah – Allah does not guide them, and for them is a punishment, most painful. 104 Only those who do not believe in Allah’s signs attribute lies and fabrications; and they themselves 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, because they have preferred the present life over the world to come, and that God guides not the people of the unbelievers. 107 God has sealed their hearts, ears and eyes and they are not aware of it. 108 and in the life to come, they will surely be the losers. 109 ۞ Then, surely thy Lord -- unto those who have emigrated after persecution, then struggled and were patient -- surely thy Lord thereafter is All-forgiving, All-compassionate. 110
