The promenade around the three domed prayer chamber, since there was no separate structure for study purpose, might have been used for open-air classes and the vaulted room with book-shelves on their walls underneath the platform may have been designed to provide residential accommodation for those who used to teach and study here.

It is an ingenious[peacock prose] way of accommodating two structures-a madrasa and a mosque in a single building which not only saved space but also a considerable amount of money.

So far known this is the earliest dated mosque in the History of Muslim Architecture in Bengal built on a high vaulted platform.

It has been suggested that Shaista Khan himself had composed the versified inscription, as his poetic nom de plume was "Talib".

The inscription reads:[3] "The rightly guided Amīr al-Umarā Shaista Khan - built this mosque for the sake of God / To the seeker (t̤ālib) enquiring its date - I said, "God's bidding is accomplished" / Year 1086 Hijri (1675-76 CE)."
