And when We substitute a verse in place of a verse - and Allah is most knowing of what He sends down - they say, "You, [O Muhammad], are but an inventor [of lies]." But most of them do not know. 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 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 Verily those who believe not in the signs of Allah - Allah shall not guide them, and unto them shall be a torment afflictive. 104 They only forge falsehood, who believe not in the signs of God, and those -- they are the 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 For they loved the life of this world more than the life to come; and God does not guide those who do not believe. 107 They are those upon whose hearts, hearing (ears) and sight (eyes) Allah has set a seal. And they are the heedless! 108 On the Day of Judgment they will certainly be lost. 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
