adhan (call to prayer)

The call broadcast from the minaret of the mosque announcing the time of prayer:

God is greatest; God is greatest; I testify that there is no God but God; I testify that there is no God but God; I testify that Muhammad is the Prophet of God; I testify that Muhammad is the Prophet of God; Hurry to prayer; Hurry to prayer; Hurry to success; Hurry to success; God is greatest; God is greatest; I testify that there is no God but God.

Before the dawn prayer, the words "prayer is better than sleep" are added.
