Adhan also variously transliterated as athan, adhane (in French), ajan/ajaan, azan/azaan (in South Asia), adzan (in Southeast Asia), and ezan (in the Balkans and Turkey), among other languages, is the Islamic call to public prayer (salah) in a mosque recited by a muezzin at prescribed times of the day.

Adhan is recited from the mosque five times daily, traditionally from the minaret. It is the first call summoning Muslims to enter the mosque for obligatory (fard) prayer (salah). A second call, known as the iqamah, summons those within the mosque to line up for the beginning of the prayers.
