Jibril ibn Umar

Jibril ibn Umar (Arabic: جبريل بن عمر; died c. 1790) was an 18th‑century Sufi scholar, jurist, and Islamic reformist from Agadez. He is most remembered as a teacher and mentor of Usman dan Fodio, Abdullahi dan Fodio, and Muhammed Bello, the leaders of the Sokoto jihad.

Jibril was known for his extreme zeal to reform Islam in the central Sudan. He argued that Muslims who committed grave sins were no longer Muslims, a view regarded by many, including his own students, as excessively radical. Despite this, he had an immense influence on the Sokoto jihad, with Usman dan Fodio later crediting him as a major inspiration for his reformist campaign in the 19th century.
