Variant: From thence the King marched towards the mountains of Nagrakote, where he was overtaken by a storm of hail and snow. The Raja of Nagrakote, after sustaining some loss, submitted, but was restored to his dominions. The name of Nagrakote was, on this occasion, changed to that of Mahomedabad, in honour of the late king. Some historians state, that Feroze, on this occasion, broke the idols of Nagrakote, and mixing the fragments with pieces of cows flesh, filled bags with them, and caused them to be tied round the necks of Bramins, who were then paraded through the camp. It is said, also, that he sent the image of Nowshaba to Mecca, to be thrown on the road, that it might be trodden under foot by the pilgrims, and that he also remitted the sum of 100,000 tunkas, to be distributed among the devotees and servants of the temple.
