(al-) al-Baghdadi (c. 825-c. 910) Eminent Muslim mystic Sufi who advocated the integration of mysticism into ordinary life.
His family was originally from Nahawand (S Iran), although he lived and taught in Baghdad. He disapproved of ecstatic mysticism and of seeking union with God, advocating instead a settled, sober way of life and a constant awareness of God. His distinctive Sufi personality stems from the ability to combine his knowledge of Islamic law learned from Imam Shafi with his Sufi commitment developed with his Sufi master al-Saqati.
