The four high dignitaries and the hakem were exempt from personal taxes, and they were invited to take part in major national ceremonies at the royal court. When Cambodia became independent, the Islamic community was placed under the control of a five-member council that represented the community in official functions and in contacts with other Islamic communities. Each Muslim community has a hakem who leads the community and the mosque, an imam who leads the prayers, and a bilal who calls the faithful to the daily prayers.
