When We substitute one revelation for another, and God knows best what He reveals, they say, "You are but a fabricator." Indeed, most of them have no knowledge. 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 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 Lo! those who disbelieve the revelations of Allah, Allah guideth them not and theirs will be a painful doom. 104 They alone invent lies who do not believe in the words of God, and they are liars. 105 Whosoever disbelieves in Allah after believing except he who is forced while his heart remains in his belief but he who opens his chest for disbelief, shall receive the Anger of Allah and for such awaits a mighty punishment. 106 This is because they prefer the life of this world to the Hereafter and because God does not guide those who deny the truth. 107 They whose hearts and whose hearing and whose sight God has sealed - it is they, they who are heedless! 108 Without doubt, in the Hereafter they will perish. 109 ۞ Those who left their homes for the cause of God after they had been persecuted, strove hard for His cause and exercised patience should know (even though they had verbally renounced their faith) that your Lord is All-forgiving and All-merciful. 110
