Although Islam has long been the religion of the Malays, their animistic and Hindu past has had strong influences upon the Malay heritage. This is evident in many of their traditional beliefs, customs and rituals, as well as in manifestations of artistic expression. Traditional practices and customary law (adat) remain important in ceremonial situations. The two best known systems are the Adat Temenggong and the Adat Perpatih. Everyday code of conduct, healing rituals and those connected with harvests, birth, ear-piercing, circumcision or the conduct of weddings manifest a fusion of cultures. The same is true of activities connected with royal ceremonies including that of the coronation. Certain rites, such as those connected with funeral, however, remain strictly Islamic in character.
