What does 'Islam' mean?This is just wrong. It is not a misnomer. The term Lutheran does not suggest that Lutherans worship Luther. The term Buddhist does not suggest that Buddhists worship Buddha. Christians do not worship Christ rather than God. Christians follow the teachings of Christ. Mohammedans follow the teachings of Mohammad. It is a completely accurate and inoffensive term.
The Arabic word 'Islam' simply means 'submission', and derives from a word meaning 'peace'. In a religious context it means complete submission to the will of God. 'Mohammedanism' is thus a misnomer because it suggests that Muslims worship Muhammad rather than God.
A 1913 dictionary defines:
Mo*ham"med*an,Mohammad founded the religion of Islam, and he also political and legal systems. The followers of Mohammad usually subscribe to his religious and his non-religious teachings. If you just want to refer to someone who subscribes to the religion of Islam, then I guess moslem or muslim would be the best term. If you want to describe someone who more broadly follows the teachings of Mohammad, then I think that Mohammedan is the more accurate term.
a. Of or pertaining to Mohammed, or the religion and institutions founded by Mohammed.
n. A follower of Mohammed, the founder of Islamism; one who professes Mohammedanism or Islamism.
I am not trying to offend anyone, or to reinvent terms. I don't think that I am saying anything here that Mohammedans would disagree with. Being a Mohammedan is more than just subscribing to a religion.
