And now that We replace one message by another - since God is fully aware of what He bestows from on high, step by step - they [who deny the truth] are wont to say: "Thou but inventest it!" Nay, but most of them do not understand it! 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 do not believe in the words of God are verily not guided by God. For them is severe punishment. 104 Only those who do not believe in Allah’s signs attribute lies and fabrications; and they themselves 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 love the life of this world more than the Hereafter; and Allah does not guide those who are ungrateful to Allah for His favours. 107 These are the ones whose hearts, ears, and eyes Allah has sealed; and they are the neglectful. 108 No doubt they shall be losers in the Hereafter. 109 ۞ Then indeed your Lord? to those who emigrated, after they were persecuted, and then strove and were patient, surely, your Lord is thereafter Forgiving, the Most Merciful. 110
