Firishta's History (Gulshan-i Ibrāhīmī) 33.4.5

33.4.5

The fatal news reached the old King, now in his eightieth year, who was so much distressed, that life became irksome to him; but bearing up against his misfortune, he sent Kei Khoosrow, his grandson (the son of the deceased), to supply the place of his father. On his arrival at Mooltan, this Prince took the command of the army, and began to provide for the defence of the frontier. The King, perceiving himself fast sinking from the weight of his affliction, sent for his son Kurra Khan from Bengal, and appointed him his successor; at the same time insisting, that he should continue with him at Dehly till his death, and appoint a deputy for his government of Bengal. To this Kurra Khan consented; but conceiving his father's illness was not likely to come so soon to a crisis as he expected, he returned to Bengal without acquainting him of his intention. This undutiful behaviour threw the old man into the deepest grief, and induced him to send for his grandson, Kei Khoosrow, from Mooltan. The Prince hastening to his presence, a council of the nobles was called, and the succession was changed in his favour, all of the officers promising to enforce Gheias-ood-Deen Bulbun's last will, in favour of this young Prince. The King, in a few days, expired, in the year 685, after a reign of 21 years.
