Abū al-Qāsim Jalāl ad-Dīn Tabrīzī (Persian: أبو القاسم جلال الدین تبریزی) was a celebrated Sufi saint of South Asia. He arrived in Bengal shortly after the start of its Muslim rule, where he propagated Islam to the local populace and spent the rest of his life. The Jaliliyyah Order, a small tariqah, is named after him, and he is considered to be the protagonist of the Sanskrit fiction (Advent of the Shaykh).
