The Cham have their own mosques. In 1962 there were about 100 mosques in the country. At the end of the nineteenth century, the Muslims in Cambodia formed a unified community under the authority of four religious dignitaries—mupti, tuk kalih, raja kalik, and tvan pake. A council of notables in Cham villages consisted of one hakem and several katip, bilal, and labi. 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. The peninsula of Chrouy Changvar near Phnom Penh is considered the spiritual center of the Cham, and several high Muslim officials reside there. Each year some of the Cham go to study the Qur'an at Kelantan in Malaysia, and some go on to study in, or make a pilgrimage to, Mecca. According to figures from the late 1950s, about 7 percent of the Cham had completed the pilgrimage and could wear the fez or turban as a sign of their accomplishment.
