The Jerrahi are a Sufi tariqah (order) derived from the Halveti order. Their founder is Hazreti Pîr Muhammad Nureddin al-Jerrahi (1678-1720), who lived in Istanbul and is buried at the site of his tekke in Karagümrük, Istanbul. Nureddin was a direct descendant of Muhammad both from his mother and father. During the Late Ottoman period, the Order was widespread throughout the Balkans, particularly Macedonia and southern Greece (Morea). The Jerrahi Order of Dervishes is a cultural, educational, and social relief organization with members from diverse professional, ethnic and national backgrounds.
