 Islam, like Judaism, has no clergy in the sacerdotal sense; there is no institution resembling the Christian priesthood.Islamic religious leaders do not "serve as intermediaries between mankind and God", have "process of ordination", nor "sacramental functions".They have been said to resemble more rabbis, serving as "exemplars, teachers, judges, and community leaders," providing religious rules to the pious on "even the most minor and private" matters.
