[3] Sabi Khan was said to have arrived to the region during the reign of Mughal emperor Jahangir as a representative of the Subahdar (Governor) of Bengal.
[5] The Mughal governor, based in Jahangir Nagar (Old Dhaka), appointed Sabi Khan as the Faujdar of Bakla in 1618.
The present Gaila Das Bari is thought to have been Sabi Khan's home due to the foundations discovered in the brick walls of the residence.
[7] Henry Beveridge records a different account, which places Sabi Khan as the son of a wealthy merchant who was kidnapped at an early age and raised in the forests of Bakla-Chandradwip.
Beveridge continues by narrating how Sabi's father was murdered many years later eventually leading to his mother escaping to the forests.
[8] Sabi Khan greatly contributed to the development of the Bakla-Chandradwip region, and signs of this can still be found in Gournadi, Wazirpur, Kotwali, Muladi and Kotalipara.
[9] During his time as faujdar, a large road was constructed from the port of Tarki to Madhabpasha (capital of Chandradwip) via Qasba, Gaila, Dhamura and Otra.
The first went from Ramdas-Hatkhola southwards to Dhamura and Otra, the second went from Kotalipara in the west towards Murshidabad and the third went from the southeast and merged with the present-day Gaila-Gaurnadi road.
