A few, people stand in the face of tyranny with endurance when they believe in the true and eternal message of Islam. This book sheds light on the life and struggle of the greatest example of endurance. Bilal bin Rabah (R) whom Islam changed from a weak slave to a great hero, stood firm in the face of oppression and hence taught generations to come how a Muslim should act when his Faith is challenged. He was the only Mu'adhdhin (caller to prayer) during the lifetime of the Prophet (S) His emblem all his life was 'Allah is One, Allah is One.'
