"...Muhammad bin Tughlaq enhanced the land revenue in a very steep manner. Barani reports: “The taxation in the Doab was increased ten and twenty times and the royal officials consequently created such abwabs or cesses and collected them with such rigour that the ryots were reduced to impotence, poverty and ruin… Thousands of people perished, and when they tried to escape, the Sultan led expeditions to various places and hunted them like wild beasts.” Ibn Battutah who visited Delhi during Muhammad bin Tughlaq’s reign, reports in his Rehla an Id celebration in the Sultan’s palace: “Then enter the musicians, the first batch being the daughters of the infidel rajas captured in war that year. They sing and dance, and the Sultan gives them away to his amirs and aizza. Then come the other daughters of the infidels who sing and dance, and the Sultan gives them away to his relations, his brothers-in-law and the malik’s sons.” At a later date, “there arrived in Delhi some female infidel captives, ten of whom the vazir sent to me”. Again, the Sultan sent to the emperor of China “one hundred male slaves and one hundred slave songstresses and dancers from among the Indian infidels”. He also reports how the Muslim commandant of Alapur “would fall upon the infidels and would kill them or take them prisoner”. The scoundrel was killed by the Hindus one day. His slaves fell upon Alapur, and “they put its male population to the sword and made the womenfolk prisoner and seized everything in it.”"
