When We exchange a verse for another and Allah knows best what He is sending down they say: 'You are but a forger' No, 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 certainly know that they say, "It is only a human being who teaches the Prophet." The tongue of the one they refer to is foreign, and this Qur'an is [in] a clear Arabic language. 103 Those who disbelieve in the signs of Allah – Allah does not guide them, and for them is a punishment, most painful. 104 It is but they who will not believe in God's messages that invent this falsehood; and it is they, they who are lying! 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 That is because they preferred the worldly life over the Hereafter and that Allah does not guide the disbelieving people. 107 Such are they whose hearts and ears and eyes Allah hath sealed. And such are the heedless. 108 On the Day of Judgment they will certainly be lost. 109 ۞ Then indeed your Lord? to those who emigrated, after they were persecuted, and then strove and were patient, surely, your Lord is thereafter Forgiving, the Most Merciful. 110
