In short, when Muhammad Bakhtiyar became aware of the nature of the country, and saw that his men were tired and exhausted, and that many had been slain and disabled in the first day’s march, he consulted with his nobles, and they resolved that it was advisable to retreat, that in the following year they might return to the country in a state of greater preparation. On their way back there was not left on all the road a single blade of grass or a bit of wood. All had been set on fire and burnt. The inhabitants of the valleys and passes had all removed far away from the road, and for the space of fifteen days not a sir of food nor a blade of grass or fodder was to be found, and they were compelled to kill and eat their horses.

It is related that this Muhammad Bakhtiyar was a Khilji, of Ghor, of the province of Garmsir. He was a very smart, enterprising, bold, courageous, wise, and experienced man… Being a bold and enterprising man, he used to make incursions into the districts of Munir (Monghir), and Behar, and bring away much plunder, until in this manner he obtained plenty of horses, arms, and men. The fame of his bravery and of his plundering raids spread abroad, and a body of Khiljis joined him from Hindustan. His exploits were reported to Sultan Kutbu-d din, and he sent him a dress and showed him great honour. Being thus encouraged, he led his army to Behar and ravaged it. In this manner he continued for a year or two to plunder the neighbourhood, and at last prepared to invade the country.

In short, Muhammad Bakhtiyar assumed the canopy, and had prayers read, and coin struck in his own name and founded mosques and Khãnkahs and colleges, in place of the temples of the heathens.
