And when We put a revelation in place of (another) revelation, - and Allah knoweth best what He revealeth - they say: Lo! thou art but inventing. Most of them know not. 101 Say, "The Holy Spirit has brought it down as truth from your Lord, so that He may strengthen those who believe, and also as guidance and as good tidings for those who submit." 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 Lo! those who disbelieve the revelations of Allah, Allah guideth them not and theirs will be a painful doom. 104 Only they invent falsehood who believe not Allah's revelations, and (only) they are the liars. 105 As for anyone who denies God after having once attained to faith - and this, to be sure, does not apply to one who does it under duress, the while his heart remains true to his faith, but [only, to] him who willingly opens up his heart to a denial of the truth: upon all such [falls] God's condemnation, and tremendous suffering awaits them: 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 Those are they whose hearts, ears, and eyes Allah has sealed up, and they take no heed. 108 They will surely be losers in the life to come, 109 ۞ Then, indeed your Lord, to those who emigrated after they had been compelled [to renounce their religion] and thereafter fought [for the cause of Allah] and were patient - indeed, your Lord, after that, is Forgiving and Merciful 110
