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 indeed We know that they (polytheists and pagans) say: "It is only a human being who teaches him (Muhammad SAW)." The tongue of the man they refer to is foreign, while this (the Quran) is a clear Arabic tongue. 103 Verily! Those who believe not in the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of Allah, Allah will not guide them and theirs will be a painful torment. 104 They only invent falsehood who do not believe in the verses of Allah, and it is those who 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 That is because they love the life of this world more than the Hereafter; and Allah does not guide those who are ungrateful to Allah for His favours. 107 Those -- God has set a seal on their hearts, and their hearing, and their eyes, and those -- they are the heedless ones; 108 Truly it is they, they who in the life to come shall be the losers! 109 ۞ Then, indeed your Lord, to those who emigrated after they had been compelled [to renounce their religion] and thereafter fought [for the cause of Allah] and were patient - indeed, your Lord, after that, is Forgiving and Merciful 110
