Muntakhab al-tawarikh 15: SULTAN ARSALAN SHAH IBN MAS‘UD IBN IBRAHIM,

15

Ascended the throne of sovereignty and seized upon the whole of his brothers with the exception of Bahram Shah who fled and went to Sultan Sinjar who was the son of his maternal uncle. In spite of all the apologies for Bahram Shah which Sultan Sinjar made the subject of several letters, Arsalan Shah would not listen to him, and eventually Sultan Sinjar raised an army against him. He gave battle with thirty thousand cavalry, and being defeated went to Hindustan. Sultan Sinjar remained forty days in Ghaznin and after presenting that country to Bahram Shah retraced his steps. Arsalan Shah having collected a large army in Hindustan proceeded thence to attack Ghaznin, and Bahram Shah not being able to withstand him sought refuge in the fortress of Bamian and with the assistance of Sultan Sinjar having again seized Ghaznin and taken Arsalan Shah captive put him to death in the year 510 H. (1116 A. D.). The reign of Arsalan Shah had lasted for a period of seven years.
