Hazrat Bellal (R)
The institution of the muezzin has existed since the time of Muhammad.
The first muezzin was a former slave Bilal ibn Rabah, one of the most trusted and loyal Sahabah (companions) of the Islamic prophet Muhammad.
He was born in Mecca and is considered to have been the first mu'azzin, chosen by Muhammad himself.
