A Khorasanian dervish who settled in Isparta in the second half of the 15th century (c. 1464/1476) as a Naqshbandi caliph. He served for over fifty years at the lodge he founded where the Ak Oluk Mosque now stands; the lodge later took on a Bektashi character. He died in 937/1521 and was buried opposite the Ak Oluk Mosque in the Hızırbey quarter named after him. (Sources: Ölmez & Gökmen, bilig 35/2005; Böcüzade, Isparta Tarihi)
