v3.c26.9

Hūshang marched to Māndū, and some combats took place between his troops and those of his cousin, but he had no means of reducing the fortress and marched off, but took possession of the kingdom by establishing military posts in the principal towns. Malik Mughīs Khaljī, said to have been descended of the elder brother of Jalāl-ud-dīn Fīrūz Khaljī of Delhi, and Malik Khizr, sons of Hūshang's paternal aunts, left Mūsā Khān and joined Hūshang, and Mūsā, who could not maintain an army without the revenues of the country, which his rival was collecting, was induced by Mughīs to vacate Māndū, which was promptly occupied by Hūshang.
