About Mohammedanism
Mohammedan is a historical term used to denote a follower of Muhammad, the Islamic prophet. It is used as both a noun and an adjective, meaning belonging or relating to, either Muhammad or the religion, doctrines, institutions and practices that he established. The word was formerly common in usage, but the terms Muslim and Islamic are more common today. Though sometimes used stylistically by some Muslims, a vast majority consider the term archaic or a misnomer, as it suggests that Muslims worship Muhammad himself instead of the God in Islam.
