"The ceiling rests on columns raised with two pillars each robbed from an earlier Hindu shrine; carved lintels from another were found embedded in the thick lime-concrete roof. Other pieces were used in the ceilings of the prayer-chamber and bastions and the pillars re-utilised in the verandahs, originally used as a madrasa, after chipping the decoration off them. The tomb was repaired later by Firuz Shah Tughluq."
