Jayapala

““He (Mahmud) scattered the army of the Hindus in one attack and took Rai Jaipal prisoner. He carried him to the distant part of his kingdom of Ghazni and delivered him to an agent of the Slave Market (dalal-i-bazar). I heard that at the command of the king (Mahmud), the Brokers of the Market, (maqiman-i-bazar in the original) sold Jaipal as a slave for 80 Dinars and deposited the money realised by the sale in the Treasury.””
