Abū al-Maʿālī Sayf al-Dīn Saʿīd b. al-Muṭahhar b. Saʿīd Bākharzī (al-Bākharzī, Persian: باخرزی (1190–1261) shortened as Sayf al-Dīn Bākharzī, was a poet, sheikh, and theologian who lived in the 13th century.
As suggested by his nisba, he was born and raised in Bakharz,[1] a district of the province of Quhistan in Khorasan, and he received his religious education in the cities of Herat and Nishapur.
Afterwards, according to the prominent poet Abdurahman Djami Boharsi (15th century), Sheikh Saif ed-Din went to Bukhara as a tutor.
Unlike his teacher, Sayf al-Din Bakharzi safely survived the Mongol invasion.
The mausoleum dedicated to him and Bayan-Quli Khan was built in the settlement called Fathabad, to the east of medieval Bukhara.
