A study of Abū al-ʿAbbās Aḥmad al-Tijānī (1735–1815) — founder of the Tijāniyya, claimant to the Seal of Muḥammadan Sainthood, and the last great spiritual figure produced by a thousand-year Moroccan Sufi civilization. Born in the Eastern Sahara, buried in Fez, followed today by fifty million across Africa and beyond — his path conquered a continent through channels Morocco had been building for centuries, and left a prayer in the city that resisted him.
