Abu Amr Muhammad ibn Ibrahim al-Zajjaji al-Naysaburi (d. 348/959) was an early Sufi associated with the Baghdad school. Born in Nishapur, he joined the circle of Junayd al-Baghdadi in Baghdad and also kept the company of masters such as Abu Uthman al-Hiri and Ruwaym ibn Ahmad. He spent a long portion of his life as a pious resident (mujawir) of Mecca; classical biographical works such as al-Qushayri's Risala and al-Sulami's Tabaqat al-Sufiyya record his death in 348 AH (959 CE). In the Mevlevi spiritual chain transmitted by Aflaki and cited in the TDV Encyclopedia of Islam ('Mevleviyye'), he is the link between Junayd al-Baghdadi and Abu Bakr al-Nassaj. As the location of his grave is not reliably known, no map pin is given.
