Muhammad ibn Abd al-Wahhab محمد بن عبد الوهاب

1703–1792 CE

Founder of the Wahhabi movement (1703–1792 CE) — a defining Islamic reform movement of the modern era.

His theological formulations were characterized by a rigorous application of scriptural texts, drawing heavily from the Quran and the Hadith, which he believed provided comprehensive guidance for a devout Muslim l…

Legacy

His theological legacy is significant and deeply contested. Supporters credit him with purifying Islamic monotheism and reviving authentic prophetic practice. Critics blame his movement for the destruction of irreplaceable historical sites (including early Islamic tombs in Medina), the narrowing of Islamic intellectual diversity, and providing theological frameworks that were later adopted beyond their original context. The Saudi-Wahhabi state he helped create controls Mecca and Medina and has …
