According to the Mahan Kosh compiled by Bhai Kahan Singh Nabha, when Sri Guru Arjan Dev Ji was due to get married, Guru Ji travelled from Goindwal Sahib and arrived here on 1st July 1589 (although the Gurdwara board incorrectly states the date as 1590).
Guru Ji was travelling to Mau Sahib(ਮੌ ਸਾਹਿਬ )to get married to Mata Ganga. Along with Guru Arjan Dev Ji the marriage group included Baba Budha Ji, Bhai Manj Ji, Bhai Shalo Ji, Mian Mir Ji, Bhai Gurdas Ji, Bhai Sang Ji and other Sikhs.
At the time, the village of Bilga only consisted of 7 mud huts. However, the villagers served Guru Arjan Sahib Ji and the marriage group with great respect and dedication for 2 days.
Guru Arjan Dev Ji was highly impressed with the hospitality the villagers provided and so gave some of his clothes as gifts. The clothes were preserved and can be seen at the Gurdwara.
A well has been preserved in the main Gurdwara, this well provided bathing water for Guru Ji while he stayed at this location. Every year, there is a great diwan on 18, 19, 20 Harh where (on the last day) the clothes of Guru Arjan Dev Ji are displayed.
