Bilal ibn Rabah

Bilal ibn Rabah (580-640 CE) was an Abyssinian (Ethiopian) companion of Prophet Muhammad and the first muezzin (caller to prayer) in Islam. Born into slavery in Mecca, Bilal was among the earliest converts to Islam. When his master Umayyah ibn Khalaf discovered his faith, he subjected Bilal to horrific torture, placing a heavy boulder on his chest under the scorching desert sun and demanding he renounce Islam. Bilal's response became one of the most iconic declarations of faith in Islamic history: he repeatedly cried out 'Ahad, Ahad' (One, One), affirming the oneness of Allah.

Abu Bakr as-Siddiq purchased Bilal's freedom, and the Prophet appointed him as the first person to call the adhan (call to prayer) in Islam. His deep, resonant voice rang out over Medina five times a day, and his adhan became synonymous with the Muslim prayer. Bilal was a constant companion of the Prophet, serving as his personal attendant and treasurer. He fought at the battles of Badr, Uhud, and all subsequent engagements.

After the Prophet's death, Bilal was so grief-stricken that he could barely bring himself to call the adhan. He left Medina and participated in the Muslim campaigns in Syria, settling in Damascus. According to some narrations, he called the adhan one final time when Umar visited Jerusalem, and everyone who heard it wept remembering the Prophet. Bilal died in Damascus around 20 AH (640 CE). His story remains a powerful testament to Islam's rejection of racism and its affirmation of human equality before Allah.
