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 And certainly We know that they say: Only a mortal teaches him. The tongue of him whom they reproach is barbarous, and this is clear Arabic tongue. 103 Lo! those who disbelieve the revelations of Allah, Allah guideth them not and theirs will be a painful doom. 104 They alone invent lies who do not believe in the words of God, and they are liars. 105 Except for those who were forced to engage in infidelity to Allah after believing the while their hearts remained firmly convinced of their belief, the ones whose hearts willingly embraced disbelief shall incur Allah's wrath and a mighty chastisement lies in store for them. 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 On the Day of Judgment they will certainly be lost. 109 ۞ Then, verily! Your Lord for those who emigrated after they had been put to trials and thereafter strove hard and fought (for the Cause of Allah) and were patient, verily, your Lord afterward is, Oft-Forgiving, Most Merciful. 110
