Bilal ibn Rabah

Bilal was a slave. An Abyssinian, dark-skinned, owned by Umayyah ibn Khalaf — one of the cruelest men in Makkah.

When Bilal embraced Islam, his master found out. Umayyah's response was to take him to the desert at midday — the most brutal heat — and lay him on the burning sand, then place a massive stone on his chest.

The command was simple: deny Muhammad ﷺ, or die under the rock.

Bilal's response, again and again, as the stone pressed down and the sun blazed: "Ahad. Ahad." — "One. One." The name of Allah's oneness. He would not say anything else.

This continued day after day.

Abu Bakr passed by, was moved, and negotiated his purchase. He bought Bilal and freed him.

Years later, when the first Muslims in Madinah debated how to call the community to prayer, the Prophet ﷺ received guidance and chose the form of the azhan. Then he asked: who will call it?

He chose Bilal — the former slave, the one who had been tortured for saying Allah's name — and gave him the highest voice in the new Muslim community.

Bilal became the first muezzin of Islam. His voice called believers to prayer five times a day from the rooftop of the mosque.

After the Prophet ﷺ died, Bilal could not complete the azhan. He would reach "Ash-hadu anna Muhammadan rasulullah" — and break. He said: "I cannot call the azhan after him."

He left Madinah and never gave the azhan again — except once. When the Muslims entered Jerusalem, Umar ibn al-Khattab asked Bilal to give the azhan. The entire city went still. Everyone who had known the Prophet ﷺ wept.
