Born in Persia. Studied Hanbali jurisprudence in Baghdad. Spent twenty-five years as a wandering ascetic in the deserts of Iraq. Became a popular preacher with his own Sufi school and center. Served as a Hanbali jurist and part-time mufti. Most universally popular saint and holy man in Islam. Recognized as the patron and founder of the Qadiri order but did not actually propagate any tariqah (order) during his lifetime; the order named after him was developed by his descendants and followers posthumously and has spread throughout the Islamic world. Has a reputation for theological soundness that has led others to claim his work as the basis for their own insights and experiences.
