Dargah Mall served Guru Har Rai and Guru Har Krishan as Diwan or manager of their household. He also served for a time in the same capacity for Guru Tegh Bahadur until he was joined by his nephew Bhai Mati Das and his brother, Bhai Sati Das who took over their uncle's duties after his retiring.
His brother was Bhai Hira Mal, also called Hiranand and his father was Bhai Paraga who had embraced the Sikh faith in the time of Guru Hargobind and had taken part in battles with the Mughal forces. Before becoming Sikhs the family were Brahmans of Kariala, in Jehlam district, about 10 kilometres from Chakwal on the road to Katas Raj, now in Pakistan. The village stands on the top of Surla hills in a part of the country known as Dhani meaning rich. A few kilometres away are the Salt Mines and coal mines of Dandot. Katas lake is nearby.
A great Hindu fair was held there upto 1947. The Hindus always selected fine places of enchanting natural beauty for their fairs, festivals and pilgrimages. The inhabitants upto 1947 were both Hindu and Muslim, all handsome, tall, robust, and strong, enjoying a good standard of living.
His nephew Bhai Mati Das was one of the Sikhs who accompanied Guru Tegh Bahadur to Delhi and Martrydom.
