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 You say: "It has been sent by divine grace from your Lord with truth to strengthen those who believe, and as guidance and good news for those who have submitted (to God)." 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 believe not in the Signs of Allah,- Allah will not guide them, and theirs will be a grievous Penalty. 104 They alone invent lies who do not believe in the words of God, and they are liars. 105 Whoso disbelieveth in Allah after his belief - save him who is forced thereto and whose heart is still content with the Faith - but whoso findeth ease in disbelief: On them is wrath from Allah. Theirs will be an awful doom. 106 This because they love the life of this world better than the Hereafter: and Allah will not guide those who reject Faith. 107 These are the ones upon whose hearts and hearing and sight God has set a seal. It is they who are heedless, 108 No doubt they shall be losers in the Hereafter. 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
