Duh. You must be kidding. The first thing Muslim invaders did was to destroy Hindu temples.
There is hardly any temple left in North India which is more than 400 years old as they are all destroyed. You wont find an old Hindu temple in Delhi which isn't damaged or destroyed.
sample this :
Here is the Persian historian Vassaf relating with elation the reduction of Cambay in Gujarat by the forces of Alauddin Khilji:
" The Muhammadan forces began to kill and slaughter on the right and on the left unmercifully, through the impure land, for the sake of Islam, and blood flowed in ********. They plundered gold and silver to an extent greater than can be conceived … They took captive a great number of handsome and elegant maidens, amounting to 20,000, and children of both sexes, more than the pen can enumerate … In short, the Muhammadan army brought the country to utter ruin, and destroyed the lives of the inhabitants, and plundered the cities, and captured their offspring, so that many temples were deserted and the idols were broken and trodden under foot, the largest of which was one called Somnat, fixed upon stone, polished like a mirror, of charming shape and admirable workmanship. The Muhammadan soldiers plundered all those jewels and rapidly set themselves to demolish the idol. The surviving infidels were deeply affected with grief, and they engaged to pay a thousand pieces of gold as ransom for the idol, but they were indignantly rejected, and the idol was destroyed, and its limbs, which were anointed with ambergris and perfumed, were cut off. The fragments were conveyed to Delhi, and the entrance of the Jama Masjid was paved with them, that people might remember and talk of this brilliant victory. ‘Praise be to God, the Lord of the worlds, Amen!
