Like the universe has a system in it, likewise Quran has a system in it. One cannot create the universe, similarly one cannot create the system Quran has for the ethical, moral and spiritual issues of humanity. it has claims as well as the reasons in it, impossible for a human to do it. Muhammad or any other person could not have authored Quran. it is authored by G-d whatever the proper name of Him in any language that a people speak. Regards
