Acceptance and Rejection of a Miracle

"Indeed those who reject the truth (the miracle of the Quran) it is all the same to them whether you warn them of the consequences of there denial they will not believe " and "This the Book in which there is no doubt, it is guidance for those who who are God-conscience" What is a miracle? An effect or extraordinary event in the physical world that surpasses all known human or natural powers and is ascribed to a supernatural cause. In Arabic the word "Mujiza" comes from "A'jiz" meaning to become weak, when the mind becomes too weak to explain an event or thing. How is a person whom Allah has chosen to communicate with humanity supposed to show to the world that he IS the messenger of God? If someone makes such a claim, people will demand something extraordinary to prove such a claim. So they are given the miracles as proofs. Seeing such a miracle should lead one to at least examine what the claims are. Upon studying the claims; the claims are so true & pure that it reminds a person of what is already within a person. However, for others it just sounds everything contrary to the practical reality and it goes against the personal interests of the person. The miracle and its teaching are so powerful as create a polarization in the entire society. Those that believe and those that do not. Those with moral interests and those with personal interests are polarized. Those with the moral interests are from the best of society, and those with personal interests are from the worst of society.
