Wahhabism is a conservative, puritanical movement within Sunni Islam that advocates a return to what it considers the purest form of Islam. Founded by Muhammad ibn Abd al-Wahhab in the 18th century, it emphasizes strict adherence to the Quran and Sunnah. Think of it as a very strict interpretation of religious texts. It rejects any practices seen as innovations or deviations from early Islamic traditions. Wahhabism has had a significant impact on the Muslim world. It's like a 'back-to-basics' approach to religion.
