The introduction of Islam to the Bengali people has generated a connection to the Arabian Peninsula, as Muslims are required to visit the land once in their lifetime to complete the Hajj pilgrimage. Several Bengali sultans funded Islamic institutions in the Hejaz, which popularly became known by the Arabs as Bangali Madaris. It is unknown when Bengalis began settling in Arab lands though an early example is that of Haji Shariatullah's teacher Mawlana Murad, who was permanently residing in the city of Mecca in the early 1800s.[3]
