This article points that the popular Ajmer Sufi Shrine (Dargah) of Khwaja Chisti in India was built on a demolished Hindu Temple (Varaha Temple). What are the historical sources for such a claim?
The link claims to have evidence from books Gulshan-i-Ibrahimi by Ferishta and the book Prithviraj Raso by Chand Bardai.
Also I found some books on ancient history by ferishta here, but it is hard to understand and get the above information.
Also are there any archaeological studies for the same?
