Moḥammad Abū Bakr Ṣiddīque al-Qurayshī was a Bengali Islamic scholar and the inaugural Pir of Furfura Sharif in West Bengal. He is regarded by his followers, who are scattered across eastern India and Bangladesh, as a mujaddid (reviver) of Islam in the region, due to his significant contributions in religious propagation via the establishment of mosques and madrasas, publication of newspapers and education development in neglected areas. He was the founding president of the sociopolitical Anjuman-i-Wazin-i-Bangla organisation, which advocated for causes such as the Khilafat Movement and Pakistan Movement. Siddique died in 1943, and his shrine is greatly venerated as one of West Bengal's most prominent Sufi centres.
