Mohsin was born into a Bengali Shia Muslim family to Haji Faizullah and Zainab Khanam in Bengal in 1143 AH (1731–1732 AD).

She was the widow of Mirza Salahuddin, the Naib-faujdar or deputy military governor of Hooghly working for the Nawab of Bengal.

She inherited a fortune from her mother Zainab, whose first husband Aga Motahar had much land and properties in Hooghly, Jessore, Murshidabad and Nadia.

One-third of his fortune was to be donated for education and religious programmes, four-ninths for pensions to the elderly and disabled, and the remaining two-ninths for the expenses of the two trustees.
