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 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 Indeed, those who do not believe in the verses of Allah - Allah will not guide them, and for them is a painful punishment. 104 Only those who do not believe in Allah’s signs attribute lies and fabrications; and they themselves are liars. 105 Except for those who were forced to engage in infidelity to Allah after believing the while their hearts remained firmly convinced of their belief, the ones whose hearts willingly embraced disbelief shall incur Allah's wrath and a mighty chastisement lies in store for them. 106 all this, because they hold this world's life in greater esteem than the life to come, and because God does not bestow His guidance upon people who deny the truth. 107 Those -- God has set a seal on their hearts, and their hearing, and their eyes, and those -- they are the heedless ones; 108 So it occurred that they are the losers in the Hereafter. 109 ۞ Then, surely thy Lord -- unto those who have emigrated after persecution, then struggled and were patient -- surely thy Lord thereafter is All-forgiving, All-compassionate. 110
