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 brought the revelation from thy Lord in Truth, in order to strengthen those who believe, and as a Guide and Glad Tidings to Muslims. 102 Surely We know well that they say about you: "It is only a human being who teaches him," (notwithstanding) that he whom they maliciously hint at is of foreign tongue, while this (Qur'an) is plain Arabic speech. 103 God will not guide those who will not believe in the signs of God; and theirs will be a painful punishment. 104 They only forge falsehood, who believe not in the signs of God, and those -- they are the 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 They are the ones upon whose hearts and hearing and eyes Allah has set a seal. They are utterly steeped in heedlessness. 108 Truly it is they, they who in the life to come shall be the losers! 109 ۞ Then, verily, thy Lord unto those who have emigrated after they had been tempted and have thereafter striven hard and endured, verily thy Lord thereafter is Forgiving, Merciful. 110
