What Religion Are/Were They?

Actually Mohametanism (or Mohammedanism or any other spelling) is not the accepted name for the religion. Islam is as monotheistic as they come and calling it Mohammedanism suggests that it is the following of Mohammed, not Allah. Lutheranism, Calvinism and other religious trends named after religious thinkers are a shorthand for those doctrinal splits since 1500.

Why would you point out that Islam is "as monotheistic as they come?" Are Jews or Christians called "Godists?" Or do we refer to them by a name that in some language means worshippers of the one true god? Muslims are indeed following Muhammad and his teaching, and up until recently in the West they were all called Mohametans which was highly accurate. But Muslims themselves insist that they only follow the one true god and are submitting to the one true god. Muslim means one who submits to god. Calling Mohametans Muslims is actually an insult to all OTHER religions as it implies that those who are non-Muslim (Christians, Jews, etc) have not submitted to god. I live in Saudi Arabia. Trust me, these people worship Mohammad whether they admit to it or not. He is every bit as revered as Jesus Christ, even if he denied being divine, and perhaps moreso. Mythology aside, they also follow the teachings and revelations of Muhammad: the Qu'ran and hadith, sura and sunna. Mohametan is very apt.
