Abd Allah ibn al-Zubayr
Muhammad al-Baqir was born in Medina, about the time when Muawiyah was trying to take the oath of allegiance for his son, Yazid. As a child, al-Baqir witnessed the Tragedy of Karbala, in which all his male relatives, except his father who was ill, were killed. As a young man, Baqir was observing the struggle of power between Umayyads, Abd Allah ibn al-Zubayr and some Shia sects; in the same time Baqir saw his father resigning from political issues.
