"What is often not easy to make out is to what extent temples were demolished and then replaced with mosques, or whether they were sometimes just converted into mosques. Or to what extent already ruined temples were disassembled and used for the construction of new buildings. Obviously, the Muslims had no qualms about re-using materials from destroyed temples, although many Muslims refer to the Qur'an as the source for a prohibition against this... Most of the mosques which were built from the materials of, and on the sites of, demolished Hindu temples, are known to the Archaeological Survey of India, and their histories are related in local traditions. What replaced the images which were effaced, destroyed or removed was God's Word, in calligraphic Arabic-in the way that the Decalogue came to rule in the churches of the West in the later sixteenth and seventeenth centuries. Inscriptions in Arabic, quoting the Qur'an, state the date and founder of the mosque as well. The seventh to eighteenth centuries have also generated an enormous mass of literary evidence of Islamic iconoclasm in the area from Transoxania and Mghanistan to Tamil Nadu and Assam, the whole of which is littered with ruins of temples and monasteries. These texts speak of the destruction of 'places of worship' (ma'iibid, biya'), 'idol-houses' (buyut al-asniim, butkhiinahii), 'fire-temples' (kunishthii, iitashkhiinahii), and their budda stone idols, 'deaf and dumb idols', and so on.... In many of the early Islamic monuments in India, plunder from Hindu or Jain temples appears to have been a common source of building material."
