"In one instance specifically Al Utbi gives an idea of the gain from the sale of captives. According to his narrative, Mahmud, after his campaign in Mathura, Mahaban and Kanauj (1018-19), returned to Ghazni with, besides other booty, 53,000 captives and each one of these was sold for two to ten dirhams. From this statement it would be safe to infer that the lowest price at which an Indian captive was sold was two, and the highest ten dirhams. It would also be safe to conclude that slaves were captured by invaders to be sold to make money; for Utbi adds that “Merchants came from different cities to purchase them so that the countries of Mawarau-n-nahr, Iraq and Khurasan were filled with them”. ... Similarly, in the Kashmir Valley (1014 C.E.), according to Utbi, the captives taken “were so plentiful that they became very cheap…” But he does not say how cheaply they were sold. ... Yet, the sale of thousands of slaves after every campaign, as the figures of captives carried away by Mahmud shows, brought good profit to the invader. No wonder that besides treasure, captives also used to be regularly carried away from India during the Ghaznavid occupation of Punjab for making extra money through their sale. This lucrative business continued, and a scion of the house, Sultan Ibrahim (1054-1099), once carried away one lakh captives to Ghazni."
