Firishta's History (Gulshan-i Ibrāhīmī) 67.2.3

67.2.3

Bahadur Khan having communicated this offer, the King was impatient to know of what the gift consisted; and the ambassadors being introduced, repeated their promise. Mahomed Shah, finding them sincere, drew up a paper in his own hand, fixing Golconda as the boundary between his kingdom and the Raja's possessions; conjuring his successors, as long as the rajas of Tulingana refrained from breaking their faith, not to molest them. The treaty being signed with the King's seal, and witnessed by the judges and the principal nobility, the Hindoo ambassadors presented to the King a throne, set with valuable jewels, originally prepared by the Raja of Tulingana as a present to Mahomed Toghluk, King of Dehly. Mahomed Shah, highly gratified, dismissed the ambassadors with marks of honour and distinction. On his return to Koolburga he held a festival, and ascending the throne in great state, caused it to be called the Tukht-i-Feroza, or cerulean throne; after which he gave audience, and conferred costly presents and titles on those officers who had merited them by their conduct during the war. The silver throne of his father was ordered, however, to be placed in the treasury, and kept as a valuable relic.
