Long ago, in the city of Makkah, there lived a young man named Bilal. Bilal had been brought to Makkah as a slave from a faraway land. He worked hard, and his life was not easy.
When Bilal heard about Islam and the Prophet Muhammad ﷺ, his heart felt happy for the first time. He believed in one Allah. He chose to become a Muslim.
But Bilal's owner was a cruel man who did not believe in Islam. When he found out that Bilal was a Muslim, he became very angry. He hurt Bilal in the hot desert sun and tried to make him give up his faith.
Even when it was very hard, Bilal stayed strong. He kept saying one word: "Ahad. Ahad." It means "One. One." He was telling everyone that Allah is One, and he would never worship anyone else.
One day, a kind companion of the Prophet ﷺ named Abu Bakr saw what was happening to Bilal. Abu Bakr paid money to set Bilal free. From that day on, Bilal was no longer a slave. He was a free Muslim, and he was with the Prophet ﷺ and his friends.
Years later, the Muslims moved to a new city called Madinah. They needed a way to call everyone to come to the masjid for prayer. The Prophet ﷺ thought about it carefully. Then he chose Bilal for a very special job.
The Prophet ﷺ said that Bilal would be the first person to call the adhan, the call to prayer. Every day, five times a day, Bilal would climb up high and call out with his beautiful, strong voice: "Allahu Akbar! Allahu Akbar!"
Bilal had once been a slave. Now his voice was the voice that brought all the Muslims together to pray. The Prophet ﷺ loved him very much.
Allah does not care where you come from, what your skin color is, or whether your family is rich or poor. Allah cares about your heart and how strong your faith is. Bilal was a slave who became one of the most loved companions of the Prophet ﷺ. His voice still echoes today, every time a Muslim hears the adhan.
From the seerah (life of the Prophet ﷺ) as recorded in multiple authentic sources, including Sahih al-Bukhari and the biographical works of Ibn Ishaq and Ibn Hisham.
