Sarai-Adl (also spelled Sarai-Adil) during Alauddin Khalji's reign was a designated market (mandi) for textiles, sugar, and other commodities. It was part of Alauddin's market regulation system where specific markets were established for different types of goods to control prices and prevent profiteering. It was not related to sarais (rest houses), courts, or the chief Qazi's office - it was a regulated commercial marketplace.
