Azan. Voice of Islam.

Azan is called out by the muezzin in the mosque five times a day, traditionally from a minaret, summoning Muslims for mandatory (fard) prayers (salah). A second call known as iqama (set up) then summons Muslims to line up for the beginning of the prayers. The main purpose behind the multiple loud pronouncements of adhan in every mosque is to make available to everyone an easily intelligible summary of Islamic belief. It is intended to bring to the mind of every believer and non-believer the substance of Islamic beliefs, or its spiritual ideology.
