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 We know very well that they say, 'Only a mortal is teaching him.' The speech of him at whom they hint is barbarous; and this is speech Arabic, manifest. 103 Indeed, those who do not believe in the verses of Allah - Allah will not guide them, and for them is a painful punishment. 104 They alone invent lies who do not believe in the words of God, and they 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 preferred the worldly life over the Hereafter and that Allah does not guide the disbelieving people. 107 They are those upon whose hearts, hearing (ears) and sight (eyes) Allah has set a seal. And they are the heedless! 108 No doubt that in the hereafter they will be the losers. 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
