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 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 very well that they say, 'Only a mortal is teaching him.' The speech of him at whom they hint is barbarous; and this is speech Arabic, manifest. 103 Verily, as for those who will not believe in God's messages, God does not guide them aright; and grievous suffering will be their lot [in the life to come]. 104 It is those who believe not in the Signs of Allah, that forge falsehood: it is they who lie! 105 Whosoever denies having once believed -- unless he is forced to do so while his heart enjoys the peace of faith -- and opens his mind to disbelief will suffer the wrath of God. Their punishment will be great, 106 For they loved the life of this world more than the life to come; and God does not guide those who do not believe. 107 God has sealed their hearts, ears and eyes and they are not aware of it. 108 Truly it is they, they who in the life to come shall be the losers! 109 ۞ Then indeed your Lord – for those who migrated after they had been oppressed, and then fought and remained patient – indeed your Lord is then, surely, Oft Forgiving, Most Merciful. 110
