After the death of Iltutmish, there was a brief lull in enslavement because of the weakened power of the sultans. In 1244, Sultan Nasiruddin Mahmud, … - Mohammed Qacim Ferichta

“In the year 402 Mahmud resolved on the conquest of Thanesar, in the kingdom of Hindustan. It had reached the ears of the king that Thanesar was held in the same veneration by idolaters, as Mecca by the faithful; that there was an old temple there, in which they had set up a number of idols, the principal of which was called [p. 30] Jagsom, and was believed to have existed over since the creation of the world. When Mahmud reached the Panjab, he was desirous that, in accordance with the subsisting treaty with Anandpal, no injury should be sustained by that prince’s country, in consequence of the Muhammadan army passing through it. An embassy was accordingly sent to inform the Raja of his design against Thanesar, and desiring him to depute his officers to remain with the army, in order that the villages and towns which belonged to him might be protected from the camp followers.

In these days he promoted a bramin, by name Seeva Dew Bhut, to the office of prime minister, who embracing the Mahomedan faith, became such a persecutor of Hindoos that he induced Sikundur to issue orders proscribing the residence of any other than Mahomedans in Kashmeer; and he required that no man should wear the mark on his forehead, or any woman be permitted to burn with her husband's corpse. Lastly, he insisted on all golden and silver images being broken and melted down, and the metal coined into money. Many of the bramins, rather than abandon their religion or their country, poisoned themselves; some emigrated from their native homes, while a few escaped the evil of banishment by becoming Mahomedans. After the emigration of the bramins, Sikundur ordered all the temples in Kashmeer to be thrown down; among which was one dedicated to Maha Dew, in the district of Punjhuzara, which they were unable to destroy, in consequence of its foundation being below the surface of the neighbouring water. But the temple dedicated to Jug Dew was levelled with the ground; and on digging into its foundation the earth emitted volumes of fire and smoke which the infidels declared to be the emblem of the wrath of the Deity; but Sikundur, who witnessed the phenomenon, did not desist till the building was entirely razed to the ground, and its foundations dug up..... "In another place in Kashmeer was a temple built by Raja Bulnat, the destruction of which was attended with a remarkable incident. After it had been levelled, and the people were employed in digging the foundation, a copper-plate was discovered, on which was the following inscription:- 'Raja Bulnat, having built this temple, was desirous of ascertaining from his astrologers how long it would last, and was informed by them, that after eleven hundred years, a king named Sikundur would destroy it, as well as the other temples in Kashmeer'…Having broken all the images in Kashmeer, he acquired the title of the Iconoclast, 'Destroyer of Idols'…"

In the year AH 829 (AD 1425), Ahmud Shah marched to reduce a rebellious zemindar of Mahoor… During this campaign, the King obtained possession of a diamond mine at Kullum, a place dependent on Gondwana, in which territory he razed many idolatrous temples, and erecting mosques on their sites, appropriated to each some tracts of land to maintain holy men, and to supply lamps and oil for religious purposes…
