"the wailing sound of the faithful being called to prayer"

The Muslim call to mandatory prayer is uttered five times a day by a muezzin from the minaret of a mosque. Named the ‘adhan’ or ‘azan’, the call has different texts of repeated phrases depending on the system of belief, but the underlying message is that of all Islam: ‘There is no deity but God, and Muhammad is the Messenger of God.’ The pronouncement is followed by a second call for the faithful to line up in the mosque for prayers.

The call is a melodious wailing chant which is broadcast through loudspeakers and can be heard across all Muslim towns at the five specified times of day.
