When We substitute one revelation for another, and God knows best what He reveals, they say, "You are but a fabricator." Indeed, most of them have no knowledge. 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 (It is not the Prophet who invents lies), it is rather those who do not believe in the signs of Allah who invent lies. They are liars. 105 Except for those who were forced to engage in infidelity to Allah after believing the while their hearts remained firmly convinced of their belief, the ones whose hearts willingly embraced disbelief shall incur Allah's wrath and a mighty chastisement lies in store for them. 106 This is because they have given preference to this life over the life to come and God does not guide disbelieving people. 107 These are they on whose hearts and their hearing and their eyes Allah has set a seal, and these are the heedless ones. 108 No doubt, in the Hereafter, they will be the losers. 109 ۞ Those who left their homes for the cause of God after they had been persecuted, strove hard for His cause and exercised patience should know (even though they had verbally renounced their faith) that your Lord is All-forgiving and All-merciful. 110
