In 1607, Qutbuddin Khan Koka was instructed to send Sher Afgan Khan to the court as he was accused of negligence and siding with Afghan rebels and transferred. Sher Afgan Khan refused to obey. Seeing this, Qutbuddin started off for Bardhaman, while he sent Ghiasa, the son of his sister, in advance to pacify Sher Afgan and bring him to the court. So upon his arrival on 30 May 1607, Sher Afgan duly went to meet him, accompanied by two men. At that moment Qutb signalled his men to arrest Sher Afgan, who stepped forward in alarm and attacked Qutbuddin sensing treachery. Qutbuddin was fatally wounded, and seeing this, his men surrounded Sher Afgan and killed him instantly.
