When We replace a message with another -- and God knows best what He reveals -- they say: "You have made it up;" yet most of them do not know. 101 Say, the Holy Spirit has brought the revelation from thy Lord in Truth, in order to strengthen those who believe, and as a Guide and Glad Tidings to Muslims. 102 We know that they say a mere mortal has taught it (the Quran) to him (Muhammad). The language of the person whom they think has taught it to him is not Arabic. This (the Quran) is in illustrious Arabic. 103 (As for) those who do not believe in Allah's communications, surely Allah will not guide them, and they shall have a painful punishment. 104 They only invent falsehood who do not believe in the verses of Allah, and it is those who are the liars. 105 Whoever disbelieves in Allah after his belief... except for one who is forced [to renounce his religion] while his heart is secure in faith. But those who [willingly] open their breasts to disbelief, upon them is wrath from Allah, and for them is a great punishment; 106 For they loved the life of this world more than the life to come; and God does not guide those who do not believe. 107 Those -- God has set a seal on their hearts, and their hearing, and their eyes, and those -- they are the heedless ones; 108 On the Day of Judgment they will certainly be lost. 109 ۞ And surely your Lord will be Most Forgiving and Most Merciful towards those who left their homes after they were persecuted, and who thereafter struggled hard and remained constant. 110
