Ajisari

In Islam, an ajisãrì is one who arouses others to pray and feast during Ramadan. The term can also refer to the practice itself. They go from house to house, as early as 2:00 AM, beating their kettle drum with a stick and singing (screaming) at the top of their voice. This is purely a religious duty; it is voluntary. Although the ajisari does not expect to be compensated by their fellow believers, they believe that Allah will reward them, in the hereafter, for forsaking their bed and discomforting themselves during the month-long fasting period.

The name derives from the Arabic word "Suhur", meaning early morning meals during the holy month of Ramadan; it is spelled and pronounced "sãrì" in Yoruba.
