Abd al-Wahhab ibn Abd al-Rahman ibn Rustam, was the second imam of the Imamate of Tahart and founder of the Wahbi Ibadism movement.
He became ruler after the death of his father, Abd al-Rahman ibn Rustam and founded an external Islamic religious movement called Wahhabism relative to his name Abd al-Wahhab.
His Ibadi Kharijite preaching is often incorrectly associated with the modern day Wahhabi movement.
[4] His father was a Persian Ibadi Muslim imam, Abd al-Rahman ibn Rustam, the founder of the Rustamid dynasty in Algeria.
He studied Abu Ubayda Muslim ibn Abi Karima's ideas and beliefs under his father, who was also a transmitter of Ibadi tradition.
