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 Say, the Holy Spirit has brought the revelation from thy Lord in Truth, in order to strengthen those who believe, and as a Guide and Glad Tidings to Muslims. 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 disbelieve in the verses of Allah, Allah does not guide them for them is a painful punishment. 104 Only they invent falsehood who believe not Allah's revelations, and (only) they are the liars. 105 He who disbelieves in Allah after his having believed, not he who is compelled while his heart is at rest on account of faith, but he who opens (his) breast to disbelief-- on these is the wrath of Allah, and they shall have a grievous chastisement. 106 This is because they prefer the life of this world to the Hereafter and because God does not guide those who deny the truth. 107 Those are the ones over whose hearts and hearing and vision Allah has sealed, and it is those who are the heedless. 108 No doubt that in the hereafter they will be the losers. 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
