v3.c26.7

Nusrat Khān treated Mālwa as a conquered country, and his rule was so oppressive and extortionate that the army expelled him, and elected as their ruler Hūshang's cousin, Mūsā Khān, who, fearing the vengeance of the king of Gujarāt, established himself in Māndū, the fortifications of which were now complete. Hūshang, on hearing of this usurpation, implored Muzaffar to restore him to his throne, swearing on the Koran that he was guiltless of his father's death, and Muzaffar, who had his own outraged authority to assert, sent his grandson Ahmad Khān, with an army to restore Hūshang.
