Bhai Dharam Singh was one of the Panj Piaré or the Five Beloved Ones. He was the son of Bhai Sant Ram and Mai Sabho, of Hastinapur, an ancient town on the right bank of the Ganges, 35 km northeast of Meerut (29 N, 77 - 45'E). Dharam Das, as he was originally named, was born around 1666. As a young man, he became acquianted with a Sikh who introduced him to the teachings of the Gurus. He left home at the age of thirty in quest of further instruction. At the Sikh shrine of Nanak Piau, dedicated to Guru Nanak, he was advised to go to Guru Gobind Singh at Anandpur, where he arrived in 1698. A few months later came the historic Vaisakhi congregation at which five Sikhs responding to the call of Guru Gobind Singh offered one after the other to lay down their lives. Dharam Das was one of those five. The Guru blessed them and called them Panj Piaré, the five beloved ones. They were anointed as the first five members of the brotherhood of the Khalsa unveiled on that day. Guru Gobind Singh then requested them to administer to him the vows of initiation. Dharam Das, who, after initiation, became Dharam Singh, took part in the battles of Anandpur. He was in Guru Gobind Singh's train when Anandpur and thereafter Chamkaur were evacuated.

During the war of succession following the death of Aurangzab on 20 February 1707, Guru Gobind Singh took the part of the rightful claimant to the imperial throne, Prince Muazzam and sent for his help Bhai Dharam Singh who with his small band of Sikhs fought in the battle of Jajau (8 June 1707). He accompanied Guru Gobind Singh to Nanded and was with him at the time of his heavenly abode on 7 October 1708. A Gurdwara there preserves the memory of jointly Bhai Dharam Singh and Bhai Daya Singh.
