Suddenly, however, great sorrow came upon him by receipt of the news that Khusrav, who in spite of his two rebellions was still his favourite son, had died at Burhānpur (January, 1622). The cause of his death has never been established beyond doubt.¹ Shāh Jahān, in reporting it, said his brother had died of colic. It is significant that the emperor, who usually added comments when recording deaths, passes over this almost in silence. Local rumour, as recorded by the English factors in the neighbourhood, definitely assigned the cause to murder and the probability of this is strengthened by Shāh Jahān’s later action.
