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 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 Surely Allah will not enable those who do not believe in the signs of Allah to be directed to the Right Way, and a painful chastisement awaits them. 104 Those who do not believe in the miracles of God invent lies and they are liars. 105 Whoever disbelieves in Allah after his belief... except for one who is forced [to renounce his religion] while his heart is secure in faith. But those who [willingly] open their breasts to disbelief, upon them is wrath from Allah, and for them is a great punishment; 106 that, because they have preferred the present life over the world to come, and that God guides not the people of the unbelievers. 107 These are they on whose hearts and their hearing and their eyes Allah has set a seal, and these are the heedless ones. 108 So it occurred that they are the losers in the Hereafter. 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
