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 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 that believe not in the signs of God, God will not guide; there awaits them a painful chastisement. 104 They alone invent lies who do not believe in the words of God, and they 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 love this world's life more than the hereafter, and because Allah does not guide the unbelieving people. 107 Such are they whose hearts and ears and eyes Allah hath sealed. And such are the heedless. 108 and in the life to come, they will surely 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
