<P> The 16th century chronicler Firishta states that although Alauddin was illiterate at the beginning of his reign, he gradually acquired the ability to read these reports, which included hastily - scribbled notes written in Persian script . Any variance in the reports from the three sources resulted in punishment for the market superintendent . The officials were aware that Alauddin received reports from three different sources, and thus, found no opportunity to deviate from the market rules . </P> <P> Even during the times of scarce rainfall, there was no increase in the grain prices during Alauddin's reign . When the rains failed, the grocers of every neighbourhood (mohalla) in Delhi were given a daily allowance of grain from the central market . The allowance was determined by the population of the neighbourhood . People were also allowed to purchase 1⁄2 mann of grain directly from the central market at one time . The allowance was higher for the landless nobles and other distinguished men, and varied on the number of their dependants . </P> <P> Alauddin ordered his officers to maintain law and order in mraket during times of drought . If a stampede resulted in the death of a helpless citizen, the law required the superintendent in - charge of the market to be punished . </P> <P> The Sera - i Adl (literally "Place of Justice") was an exclusive market in Delhi for manufactured and imported goods . The goods sold at Sera - i Adl included cloth, sugar, herbs, dry fruits, butter (including ghee) and lamp - oil . </P>
