And when We change (one) communication for (another) communication, and Allah knows best what He reveals, they say: You are only a forger. Nay, most of them do not know. 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 Those who disbelieve in the verses of Allah, Allah does not guide them for them is a painful punishment. 104 It is only those who believe not in the signs of Allah who fabricate lie, and those! they are the 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 This is because they prefer the life of this world to the Hereafter and because God does not guide those who deny the truth. 107 God has sealed their hearts, ears and eyes and they are not aware of it. 108 On the Day of Judgment they will certainly be lost. 109 ۞ Then lo! thy Lord - for those who became fugitives after they had been persecuted, and then fought and were steadfast - lo! thy Lord afterward is (for them) indeed Forgiving, Merciful. 110
