Ahmad al-Rifaʽi
Aḥmad ibn ʽAlī al-Rifāʽī (Arabic: أَحْمَد ابْن عَلِي ٱلرِّفَاعِي) was a Sunni Muslim preacher, ascetic, mystic, jurist, and theologian, known for being the eponymous founder of the Rifaʽi tariqa (Sufi order) of Islam. The Rifaʽi order had its greatest following until it was overtaken by the Qadiri order. The Rifaʽi order is most commonly found in the Arab Middle East but also in Turkey, the Balkans and South Asia.
His tomb and shrine is located at a mosque bearing his namesake in Al-Rifai, a town at southern Iraq near Baghdad.
