Men Around The Prophet
Abu Dhar al-Ghifari
S1 E6:
Abu Dahr hears of the arrival of the Prophet, and due to this lack of belief in the gods of his people and his belief that there is one God, he went to see the Prophet. He meets Ali, and after some reservation, tells Ali about his desire to meet the Prophet. After meeting the Prophet he embraces Islam, and is sent back to his people and keeps his conversion a secret until further instruction.
