Answer:
Nizam's hands were burned.
Nizam and Dastan talked about who killed Sharaman. Dastan said that he thought his brother Tus was responsible for Sharaman's death. Dastan claimed Tus knew about the dagger's power, which was turning back time, which would allow him to take the throne. Dastan then noticed the burns on Nizam's hands, and asked him how his hands were burned. Nizam said that they were burned because he was trying to take the robe off Sharaman while Sharaman was being burned. Dastan knew that Nizam did not try to take the robe off of Sharaman, making him responsible for the king's death.
