Abd al-Aziz ibn Baz
In 1979, 400–500 Islamist insurgents, using smuggled weapons and supplies, took over the Grand mosque in Mecca, called for an overthrow of the monarchy, denounced the Wahhabi ulama as royal puppets, and announced the arrival of the "Mahdi" of "end time". The insurgents deviated from Wahhabi doctrine in significant details, but were also associated with leading Wahhabi ulama (Abd al-Aziz ibn Baz knew the insurgent's leader, Juhayman al-Otaybi).
