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, [O Muhammad], "The Pure Spirit has brought it down from your Lord in truth to make firm those who believe and as guidance and good tidings to the Muslims." 102 And We know well that they say: Only a man teacheth him. The speech of him at whom they falsely hint is outlandish, and this is clear Arabic speech. 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 only those who believe not in the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of Allah, who fabricate falsehood, and it is they who are liars. 105 The one who disbelieves in Allah after accepting faith – except him who is forced to and whose heart is still firmly upon faith – but whoever is wholeheartedly a disbeliever, upon them is the wrath of Allah; and for them is a great punishment. 106 This is because they have given preference to this life over the life to come and God does not guide disbelieving people. 107 Such are they whose hearts and ears and eyes Allah hath sealed. And such are the heedless. 108 No doubt they shall be losers in the Hereafter. 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
