Take the following as truth: The Tomara Rajputs made it their capital in 736, with the name of Dhillika, and it was a focus of clan wars until the Muslims conquered it and Qutb-ud-din Aybak set up his sultanate in 1206.
Then the following statement: "The name of Dhillika was changed by Qutb-ud-din Aybak." is true, false, or inconclusive?
