Multan, which had been under Durrani rule since 1752, had been embroiled in a state of political unrest after Timur Shah Durrani deposed its governor Shuja Khan in April 1772 and appointed Haji Sharif Khan.
However, due to his indolence he was deposed as well and Sharif Beg Taklu was appointed to Multan.
The siege had already gone on for eighteen days by the time they arrived; the forces of Bahawalpur were defeated and Shuja Khan fled to Shujabad.
Muzaffar Khan asked for help from Timur Shah against him who invaded Punjab and captured Multan from Diwan Singh on February 18, 1780.
However, he allowed Diwan Singh to depart safely with his family, and Muzaffar Khan was appointed the next governor of Multan.
