According to Sunni and Shia tradition, Abdullah bin Saba' was a Yemenite Jew from the Arab Himyar tribe who converted to Islam during Uthman's reign. Because of his exaggerated reverence for Ali, he is traditionally considered as the first of the ghulāt. In accounts collected by Sayf ibn Umar, Ibn Saba' and his followers (the Saba'iyya) are said to be the ones who enticed the Egyptians against Uthman and were responsible for breaking the near-settlement at the Battle of the Camel.
