The History of Shēr Shāh (Tārīkh-i Shērshāhī) 3.17.7

3.17.7

In addition to sarkar Sambhal, Sher Shah gave him the parganas of Kant and Gola for his family, and ordered him to maintain five thousand horse, and placed also Nasir Khan under him. When Sher Shah dismissed 'Isa Khan to go to sarkar Sambhal, he said, "I am now at my ease regarding the whole country from Dehli to Lucknow." Masnad 'Ali, on his arrival at Sambhal, found Nasir Khan had seized Bairam Beg, the keeper of the seals to the Emperor, who afterwards in the time of the Emperor Akbar received the title of Khan-khanan. The reason of Bairam Beg being in Sambhal was as follows. When the army of the Emperor Humayun was dispersed, Bairam Beg went to Sambhal, having formed an intimate friendship with Mian 'Abdu-l Wahhab, son of Mian 'Azizu-lla Danishmand, one of the chief men of the city of Sambhal. 'Abdu-l Wahhab, from fear of Nasir Khan, dared not keep him in the city, but made him over to the Raja of Lukhnor, by name Mitr Sen. The Raja kept him for some time in the northern part of his country, where there is much jungle. Nasir Khan was informed that Bairam Beg was with Mitr Sen, so he wrote to the Raja that he must bring Bairam Beg to him. The Raja, from fear and dread of Sher Shah, surrendered him to Nasir Khan, who was desirous of putting him to death.
