Adhan (Azaan) (أَذَان) is the Islamic call to prayer, recited by the muezzin. The root of the word is ʼḏn "to permit", and another derivative of this word is uḏun, meaning "ear".

Adhan is called out by the muezzin from a minaret of a mosque five times a day summoning Muslims for fard (mandatory) salah (prayers). There is a second call known as iqama that summons Muslims to line up for the beginning of the prayers.
