 Despite the fact that the Duano' people have long been advocates of Islam, they are not diligent in daily prayers, nor do they visit mosques regularly, and do not usually attend to Friday prayers.It happens that during the execution of Muslim rituals, the Duano' people are always carefree, and in turn, offending the feelings of other believers.Another norm not seen in the Duano' people is also the typical of Muslims social segregation by gender.
