Westernized terms for Muslims, both inaccurate and offensive, because they suggest that Muslims are followers of Mu ammad , rather than worshippers of God; and also because al-Mu ammad ya (‘Muhammadians’) are members of sects regarded as heretical by mainstream Islam (though in Indonesia it is the name of an orthodox reforming movement, which has adapted Western institutions, e.g. Boy Scouts, to Muslim ends).
