A prolific writer, Syed Ibrahim was learned in many areas of Islam, though he was particularly focused on
tasawwuf (Islamic mysticism). For his knowledge he was styled
Danishmand (wise), the title he is most commonly associated with. Under Danishmand’s guidance, the
Hindu Rajput nobleman Kalidas Gazdani converted to Islam. Gazdani took the name Sulaiman Khan and later became the father of the famous
Isa Khan, who led the
Baro-Bhuyan in rebellion against the
Mughal Empire. Syed Ibrahim was also a noted scholar in the
Persian and
Arabic languages. He was recognised for these achievements by the
Emperor of Delhi, from whom he received the title
Malik al-Ulama (King of Scholars), and was also known by the honorific
Qutb-ul-Ashiqeen (Pivot of Lovers). At some point, Danishmand was granted land tax-free in
Sonargaon by the
Sultan of Bengal, later transferring there from his previous holdings in
Taraf in
Greater Sylhet. Here, he established a
khanqah from which he preached Islam. This practise was continued by his descendants as well as his spiritual successors. He was buried in Sonargaon, near the 15th century
Fath Shah's Mosque in a tomb complex he shares with several family members and other Islamic figures. It is considered a sacred site and is commonly visited by devotees. ==Family==
