The Chachnāma (Fatḥnāma-yi Sind) 11: Chach asks Budhíman, the minister, questions concerning the government.

Budhíman, the minister, bowed his head to the ground, and said, "May Rái Chach live for ever, and may it be known to him, that this government was under the dominion of a sole king, and his chiefs were always obedient to him. When the country was ruled by Síharas, son of Diwáíj, and when he was conquered by the army of Fárs, Sáhasi succeeded to the empire. He similarly appointed all the four rulers to their territories, expecting them to exert themselves in the collection of the revenue and the protection of the country.
