Adhai Din Ka Jhonpra

"Its very name ‘Adhai Din Ka Jhopra would seem to point directly to the astonishing rapidity of its erection, and as this could only have been affected by the free use of the ready dressed materials of prostrated Hindu temples. ... Altogether, there were 344 pillars, but each of these represented at least two of the original pillars. The actual number of Hindu columns could not have been less than 700, which is equivalent to the spoils of from 20 to 30 temples."

"Adhai Din Ka Jhonpra mosque in Ajmer is an early instance of demolition of temples. Built at the instance of the Sufi saint Moinuddin Chishti, allegedly peaceful and secular, by razing a temple of goddess Sarasvati and a Vidyapeeth by Qutubuddin Aibak after Prithviraj’s defeat."
