Explanation

The Chachnama takes its name from Raja Chach of Sindh, whose son Dahar stood against the Arabs (led by Muhammad bin Qasim).

The Chachnama was originally written by Kazi Ismail, the first Kazi of Alor appointed by Muhammad Qasim after the conquest of Sindh and translated into Persian by Ali bin Mohammad Kufi in 1224-26 A.D.
