The people of Budhiah and the headmen of the neighbouring places came forward to receive him, and he alighted at their request in front of the fort. When Bachehrá made an exit, and the Samani party placed their heads under the yoke of allegiance, Muhammad Kásim entered the fort of Siwistán. He appointed his own officers and agents to carry on the state affairs, and he left the suburban towns also in their charge. He collected silver and gold wherever he could find them, and also secured ornaments and cash from the people, excepting those of the Samani party with whom he had made a solemn compact. He then distributed among the army of Islám what was due to them out of the spoils, and taking one-fifth gave it to the treasurer of Hajjáj, and sent the booty and the slaves, with a report of his victory to Hajjáj, and himself remained there. After two or three days, when he was free from the work of distribution and had given away the army’s share as well as the Khalifah’s one-fifth, he proceeded to the fortified town of Sisam in pursuit of Bachehrá. The people of Budhiah and the ruler of Siwistán arrayed themselves in battle. Muhammad Kásim posted a party of men under his Siwistán agent in the outskirts, and himself with the remaining army alighted at a place called Budhan on the bank of the Kanbah. The suburban residents of the place were all káfirs. When they saw the army of Islám, they conspired to make a nocturnal attack on the enemy and put them into confusion.
