"Muhammad advanced to Alsaka, a town on this side of the Biyas, which was captured by him, and is now in ruins. He then crossed the Biyas, and went towards Multan, where, in the action which ensued, Zaida, the son of ‘Umur, of the tribe of Tai, covered himself with glory. The infidels retreated in disorder into the town, and Muhammad commenced the siege, but the provisions being exhausted, the Musulmans were reduced to eat [p. 24] asses. Then came there forward a man who sued for quarter, and pointed out to them an aqueduct, by which the inhabitants were supplied with drinking water from the river of Basmad. It flowed within the city into a reservoir like a well, which they call talah. Muhammad destroyed the water-course; upon which the inhabitants, oppressed with thirst, surrendered at discretion. He massacred the men capable of bearing arms, but the children were taken captive, as well as the ministers of the temple, to the number of six thousand. The Musulmans found I there much gold in a chamber ten cubits long by eight broad, and there was an aperture above, through which the gold was poured into the chamber. Hence they call Multan “the Frontier of the House of Gold,” for farj means “a frontier.”4 The temple (budd) of Multan received rich presents and offerings, and to it the people of Sind resorted as a place of pilgrimage. They circumambulated it, and shaved their heads and beards. They conceived that the image was that of the prophet Job, God’s peace be on him!"
