„The Sultan then departed from the environs of the city, in which was a temple of the Hindus. The name of this place was Maharatu-l Hind. He saw there a building of exquisite structure, which the inhabitants said had been built, not by men, but by Genii, and there he witnessed practices contrary to the nature of man, and which could not be believed but from evidence of actual sight. The wall of the city was constructed of hard stone, and two gates opened upon the river flowing under the city, which were erected upon strong and lofty foundations to protect them against the floods of the river and rains. On both sides of the city there were a thousand houses, to which idol temples were attached, all strengthened from top to bottom by rivets of iron, and all made of masonry work; and opposite to them were other buildings, supported on broad wooden pillars, to give them strength.
In the middle of the city there was a temple larger and firmer than the rest, which can neither be described nor painted. The Sultan thus wrote respecting it: - "If any should wish to construct a building equal to this, he would not be able to do it without expending an hundred thousand, thousand red dinars, and it would occupy two hundred years even though the most experienced and able workmen were employed."...
The Sultan gave orders that all the temples should be burnt with naptha and fire, and levelled with the ground.“
