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 (O Muhammad SAW) Ruh-ul-Qudus [Jibrael (Gabriel)] has brought it (the Quran) down from your Lord with truth, that it may make firm and strengthen (the Faith of) those who believe and as a guidance and glad tidings to those who have submitted (to Allah as Muslims). 102 We know indeed that they say, "It is a man that teaches him." The tongue of him they wickedly point to is notably foreign, while this is Arabic, pure and clear. 103 God will not guide those who will not believe in the signs of God; and theirs will be a painful punishment. 104 Only those who do not believe in Allah’s signs attribute lies and fabrications; and they themselves are 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 that, because they have preferred the present life over the world to come, and that God guides not the people of the unbelievers. 107 Those are they whose hearts, ears, and eyes Allah has sealed up, and they take no heed. 108 Assuredly in the Hereafter they are the losers. 109 ۞ Then, verily, thy Lord unto those who have emigrated after they had been tempted and have thereafter striven hard and endured, verily thy Lord thereafter is Forgiving, Merciful. 110
