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 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 And indeed, full well do We know that they say: "It is but a human being that imparts [all] this to him! - [notwithstanding that] the tongue of him to whom they so maliciously point is wholly outlandish, whereas this is Arabic speech, clear [in itself] and clearly showing the truth [of its source]. 103 Those who disbelieve in the signs of Allah – Allah does not guide them, and for them is a punishment, most painful. 104 They only forge falsehood, who believe not in the signs of God, and those -- they are the 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 They are the ones whose hearts and ears and eyes have been sealed by God; and these are the heedless. 108 No doubt, in the Hereafter, they will be the losers. 109 ۞ And surely your Lord will be Most Forgiving and Most Merciful towards those who left their homes after they were persecuted, and who thereafter struggled hard and remained constant. 110
