Bilal bin Rabah

Bilal bin Rabah was the muezzin of Mohammed the Messenger of Allah, peace and blessings of Allah be upon him. When the prophet died, Bilal decided that he will never call for the prayer again. But after the conquest, Bilal bin Rabah's voice rang out with the azan in Al-Aqsa Mosque, and this indicates how great the status of Jerusalem is in the hearts of Muslims.
