Alauddin gave great importance to his soldiers because it was they who could defend the Sultanate from outsiders. He decided to pay their salaries in cash rather than iqtas. The soldiers would buy their supplies from merchants in Delhi and it was thus feared that merchants would raise their prices. To stop this, Alauddin controlled the prices of goods in Delhi. For this Alauddin instructed officers to carefully survey prices. The merchants who did not sell their goods at the prescribed rates were punished.
