Qiran-us-sadin is the first historical masnavi of Amir Khusrau, the mediaeval Sufi mystic and poet.
Written in verse in 1289, it describes the much talked about meeting between Bughra Khan, a Bengal Sultan and his son Kaiqubad (Kaiqubad), the last ruler of the Mamluk dynasty of Delhi Sultanate. Bughra Khan, who was appointed governor of Bengal by his father Balban, declined to be the Delhi Sultan and instead became an independent ruler of Bengal after the death of his father in 1287. Balban was succeeded by Kaiqubad on the throne of Delhi Sultanate.
Qiran-us-sadin was written on the instructions of Kaiqubad.
