When Dábúya died, he left a son, who, under the style and title of Dhu`l-Manáqib Farrukhán-i-Buzurg, subjugated Ṭabaristán even as far as Níshápúr (in Khurásán), reduced the people to his allegiance, and, by building and cultivation, raised the country to a condition of prosperity which it had never before enjoyed, and repeatedly repelled the coveteous Turkish raiders. Then the Daylamites revolted against him, and compelled him to flee to ´Amul, where, in a castle then called Fírúz-Khusra, but now Fírúz-ábád, distant two parasangs from that city (f. 75a), he fortified himself. The Daylamites besieged him, and hoped to starve out him and his garrison, but he ordered his people to knead clay into the shape of loaves of bread and set these loaves on the walls in sight of the besiegers, who, thinking them to be bread, and despairing of being able to reduce so well provisioned a place, withdrew to Daylam, whereupon Farrukhán emerged from his fortress and followed them, con­structing in the way which led to their country dykes, ditches and canals which rendered the road impassable to horsemen.
