Beyond destruction and desecration, the sultans of the Delhi Sultanate in some cases had forbidden reconstruction of damaged Hindu, Jain and Buddhist temples, and they prohibited repairs of old temples or construction of any new temples. In certain cases, the Sultanate would grant a permit for repairs and construction of temples if the patron or religious community paid jizya (fee, tax). For example, a proposal by the Chinese to repair Himalayan Buddhist temples destroyed by the Sultanate army was refused, on the grounds that such temple repairs were only allowed if the Chinese agreed to pay jizya tax to the treasury of the Sultanate. In his memoirs, Firoz Shah Tughlaq describes how he destroyed temples and built mosques instead and killed those who dared build new temples. Other historical records from "wazirs", "amirs" and the court historians of various Sultans of the Delhi Sultanate describe the grandeur of idols and temples they witnessed in their campaigns and how these were destroyed and desecrated.
