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 Say: The Holy spirit has revealed it from your Lord with the truth, that it may establish those who believe and as a guidance and good news for those who submit. 102 We know very well that they say: 'A mortal teaches him' The tongue of him at whom they hint is a nonArab; and this is a clear Arabic tongue. 103 Those who believe not in the Signs of Allah,- Allah will not guide them, and theirs will be a grievous Penalty. 104 They alone invent lies who do not believe in the words of God, and they are 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 This is because the worldly life was dearer to them than the Hereafter; and because Allah does not guide such disbelieving people. 107 They are the ones whose hearts and ears and eyes have been sealed by God; and these are the heedless. 108 No doubt that 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
