Which Delhi Sultan introduced a system of price control in the markets and maintained a large standing army paid in cash?

Alauddin Khalji fixed prices of grain, cloth and horses, appointed market superintendents (shahna-i-mandi) and set up granaries to support a large standing army paid in cash from the treasury. Iltutmish introduced the silver tanka and iqta system, Balban stressed court discipline and kingship, and Firoz Shah Tughlaq is known for canals and public works rather than price control.
