 Despite his teachings being rejected and opposed by many of the most notable Sunni Muslim scholars of the period, including his own father and brother, Ibn 'Abd al-Wahhab charted a religio-political pact with Muhammad bin Saud to help him to establish the Emirate of Diriyah, the first Saudi state, and began a dynastic alliance and power-sharing arrangement between their families which continues to the present day in the Kingdom of Saudi Arabia.
 The Al ash-Sheikh, Saudi Arabia's leading religious family, are the descendants of Ibn ʿAbd al-Wahhab, and have historically led the ulama in the Saudi state, dominating the state's clerical institutions.
