The historical book, "Twarikh Khasa" chronicles, "Nawab usman Khan of Sadhora was so cruel and fanatical that he used to have cows slaughtered and uneatable parts of cows he would have them thrown into the Hindus homes. He never allowed them to cremate their dead and forcibly matched Hindu brides to Musalmen. The Jazia was collected in most humiliating ways so that they might be more easily converted to Islam."
