He accomplished democracy among the Jahili society (Jahiliyyah, Pre-Islamic Period of Ignorance) and he worked sincerely and efficiently to build the society of justice and development on Earth. He is the Prophet who announced the completion of Prophecies and announced the end of depending on Heaven in building the earth. It is the end of paranormal haze; and the beginning of facts era; the end of Ghaib (the unseen) era and the beginning of observation era; the end of superstition era and the beginning of reason (nous) era.
