Sarfaraz's father, Shuja-ud-Din Muhammad Khan, then the Subahdar of Orissa, getting to know it arrived at Murshidabad, the capital of the Nawabs of Bengal with a huge army.

To avoid a conflict in the family the dowager Begum of the Nawab asked Shuja-ud-Din to ascend to the Masnad after Sarfaraz abdicated in favour of his father.

On hearing of Sarfaraz's accession to the Masnad, Shuja-ud-Din Muhammad Khan, the Diwan Nazim of Orissa, marched at the head of a large army towards Murshidabad.

To avoid a conflict in the family, the dowager Begum of Murshid Quli Khan intervened; and her son-in-law Shuja-ud-Din ascended to the Masnad of Bengal.

During his tenure, the city of Jahangirnagar saw rapid economic growth through agriculture and trade - the greatest since the time of Governor Shaista Khan.

These incensed noblemen, intent on giving vent to their enmity and hatred against Haji Ahmed, caused caricatures to be drawn of him, and eventually effected in Sarfaraz Khan's mind a total alienation of regard towards him.

Haji Ahmed dreading the influence of his numerous enemies, endeavoured to gain strength to oppose them; he therefore wrote to his brother Alivardi Khan, magnifying trifles exceedingly in the representation.

He wrote to him a secret letter, in which he requested to have the patents of the three provinces transferred to himself, under promise of sending to court a present of a crore (ten million) of rupees, besides the whole of Sarfaraz Khan's wealth.

To effect this, he required an imperial commission directed to himself, empowering him to wrest the three provinces out of the hands of the present viceroy, Sarfaraz Khan.

At the same time, he had the art to give Sarfaraz Khan public notice of his project, though he in reality waited ready to avail himself of the first opportunity to effect his true purpose.

Initially satisfied, Sarfaraz Khan eventually decided to march on the head of his army and arrived at the town of Comrah on 9 April 1740.

He founded the new Afshar Dynasty According to the Archaeological Survey of India, the Tomb of Nawab Sarfraz Khan at Naginabagh is a State Protected Monument (Item no S-WB-80).
