Muhammad ibn ʿAbd al-Wahhab (Arabic: محمد بن عبد الوهاب‎; 1703 – 22 June 1792) was an Arabian Islamic Salafi[citation needed] scholar. His pact with Muhammad bin Saud helped to establish the first Saudi state and began a dynastic alliance and power-sharing arrangement between their families which continues to the present day. The descendants of Ibn ʿAbd al-Wahhab, the Al ash-Sheikh, have historically led the ulama in the Saudi state, dominating the state's clerical institutions. - Wiki.
