Al-Biruni quotes
They (the Hindus) differ from us in religion... There is very little disputing about theological topics among themselves; at the most they fight with words, but they will never stake their soul or body or their property on religious controversy. ... in all manners and usages they differ from us to such a degree as to frighten their children with us... and as to declare us to be devil's breed and our doings as the very opposite of all that is good and proper, ....they call all foreigners as mleccha, i.e. impure, and forbid having any connection with them, be it by intermarriage or any other kind of relationship, or by sitting, eating, and drinking with them, because thereby they think, they would be polluted... They are not allowed to receive anybody who does not belong to them, even if he wished it, or was inclined to their religion.

The linga he raised was the stone of Somnath, for soma means the moon and natha means master, so that the whole word means master of the moon. The image was destroyed by the Prince Mahmud, may God be merciful to him! - AH 416. He ordered the upper part to be broken and the remainder to be transported to his residence, Ghaznin, with all its coverings and trappings of gold, jewels, and embroidered garments. Part of it has been thrown into the hippodrome of the town, together with the Cakrasvamin, an idol of bronze, that had been brought from Taneshar. Another part of the idol from Somanath lies before the door of the mosque of Ghaznin, on which people rub their feet to clean them from dirt and wet.

The Hindus believe with regard to God that he is one, eternal, without beginning and end, acting by free-will, almighty, all-wise, living, giving life, ruling, preserving; one who in his sovereignty is unique, beyond all likeness and unlikeness, and that he does not resemble anything nor does anything resemble him.
