The Chachnāma (Fatḥnāma-yi Sind) 12: Chach asks wazir Budhiman about the extent of his kingdom.

Then Chach called the Taki wazir Budhiman, and questioned him about the limits of the kingdom of Sahiras. “O able wazir and wise counsellor,” said he, “do you know what the boundaries of the country of Sind were when it was under the rule and sway of the senior Rai Sahasi? What are those four divisions which formed its limits in every direction? Give us all the information you have about them, so that I may go to” those limits, and ascertain whether the people there are disposed to be obedient or adverse to me, and, if any one is refractory or disobedient, I may take measures to remove him, and see that all bring their heads under my yoke, and no opponent or rebel finds his way into my kingdom, or sets my authority at naught.”
