When We substitute one revelation for another,- and Allah knows best what He reveals (in stages),- they say, "Thou art but a forger": but most of them understand not. 101 (Muhammad), say, "The Holy Spirit has brought the Quran from your Lord to you in all truth to strengthen the faith of the believers and to be a guide and glad news for the Muslims". 102 And certainly We know that they say: Only a mortal teaches him. The tongue of him whom they reproach is barbarous, and this is clear Arabic tongue. 103 Those who disbelieve in the signs of Allah – Allah does not guide them, and for them is a punishment, most painful. 104 Only they invent falsehood who believe not Allah's revelations, and (only) they are the liars. 105 Whoever disbelieved in Allah after his belief, except him who is forced thereto and whose heart is at rest with Faith but such as open their breasts to disbelief, on them is wrath from Allah, and theirs will be a great torment. 106 that, because they have preferred the present life over the world to come, and that God guides not the people of the unbelievers. 107 Such are they whose hearts and ears and eyes Allah hath sealed. And such are the heedless. 108 Truly it is they, they who in the life to come shall 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
