Wahhabism by Hamid Algar

Wahhabism, a peculiar interpretation of Islamic doctrine and practice that first arose in mid-eighteenth century Arabia, is sometimes regarded as simply an extreme or uncompromising form of Sunni Islam. This is incorrect, for at the very outset the movement was stigmatized as aberrant by the leading Sunni scholars of the day, because it rejected many of the traditional beliefs and practices of Sunni Islam and declared permissible warfare against all Muslims that disputed Wahhabi teachings.
