This new source of information not only provides interesting information on the rise and fall of the Rohilla chiefs in Katehar region (Rohilkhand) but also is the first one ever written in Janbhasha (prose). Besides the rise of Jat power under Maharaja Suraj Mal, the conflict between the Bangash Pathans of Farrukhabad and the Wazir, Safdar Jung, the third battle of Panipat fought between the Marathas and Ahmad Shah Abdali, the treacherous role played by some of the allies of the Marathas and Najib ud-Daula's relations with Suraj Mal and the Maratha chiefs, also receive detailed treatment. This work being the first history of the Rohilla chiefs of Katehar not only serves as corrective to Persian histories but also contains much of importance for those who are interested in the history of the progress of the regional dialect called Hindwi out of which evolved the modern Urdu and Hindi languages. If the text is transferred from its Urdu script into that of Devanagari, it will be taken as the first book ever written in Hindi prose.
