The Chachnāma (Fatḥnāma-yi Sind) 26: Chach marches to Kirman and defines the boundary of Makran.

26

When Chach had settled these matters, he made up his mind to determine the boundary of Kirman, which was adjacent to the possessions of the chiefs of Hind. At this time two years had elapsed since the Hijra of the Prophet of God,—may peace be to him. After the death of Kisra bin Hurmaz bin Fars, and the disruption of his dominions, the management of the affairs of the kingdom devolved upon a woman. When Chach was informed of this, he determined to go to Kirman with a considerable force. At an auspicious time, which was fixed by the astrologers, he marched towards Armabel, and when he arrived there the chief of the place came to receive him. He was a Buddhist priest, and had descended from the representatives of Rai Siharas, king of Hind, whom the Rai had raised up with great kindness and favour. From change of time he had become refractory, and had revolted from his allegiance. He came forth to meet Chach, when a treaty was made, and cordiality and friendship was established between them. Chach proceeded from thence to Makran. Every chief that was met offered his submission. When he had crossed the province of Makran and the hills, he entered another district. There was an old fort here called Kanarpur. He ordered it to be rebuilt; and according to the Hindu custom a naubat of five musical instruments, was ordered to be played every evening and morning in the fort. He collected all the people of the surrounding villages, and completed the building. He marched from this place towards Kirman; and halted on the banks of a river which runs between that country and Makran. There he fixed the eastern boundary, that is, the boundary between Makran and Kirman, and planted numerous date trees there upon the banks of the stream, and he set up a mark, saying, "this was the boundary of Hind in the time of Chach bin Silaij bin Basabas." Now that boundary has come into our possession.
