Wahhabism () is an Islamic revivalist movement and doctrine that started within Sunni (primarily Hanbali) Islam and it is associated with the teachings of Muhammad ibn Abd al-Wahhab. It has been variously described as "orthodox", "puritan(ical)"; and as an Islamic "reform movement" to restore "pure monotheistic worship" by devotees.
