Hasan Nizami writes that after the suppression of a Hindu revolt at Kol (Aligarh) in 1193 AD, Aibak raised “three bastions as high as heaven with their heads, and their carcases became food for beasts of prey. The tract was freed from idols and idol-worship and the foundations of infidelism were destroyed.” In 1194 AD Aibak destroyed 27 Hindu temples at Delhi and built the Quwwat-ul-Islãm mosque with their debris. According to Nizami, Aibak “adorned it with the stones and gold obtained from the temples which had been demolished by elephants”. In 1195 AD the Mher tribe of Ajmer rose in revolt, and the Chaulukyas of Gujarat came to their assistance. Aibak had to invite re-inforcements from Ghazni before he could meet the challenge. In 1196 AD he advanced against Anahilwar Patan, the capital of Gujarat. Nizami writes that after Raja Karan was defeated and forced to flee, “fifty thousand infidels were despatched to hell by the sword” and “more than twenty thousand slaves, and cattle beyond all calculation fell into the hands of the victors”. The city was sacked, its temples demolished, and its palaces plundered. On his return to Ajmer, Aibak destroyed the Sanskrit College of Visaladeva, and laid the foundations of a mosque which came to be known as ADhãî Din kã JhoMpaDã. Conquest of Kalinjar in 1202 AD was Aibak’s crowning achievement. Nizami concludes: “The temples were converted into mosques… Fifty thousand men came under the collar of slavery and the plain became black as pitch with Hindus.”
