In 1705 Shri Guru Gobind Singh Ji went to Machiwala after leaving Anandpur Sahib. During those severe hardship days some Rajas refused even to offer help to Guru Sahib due to the fear of death as Aurangazeb was after the life of Guru Sahib and his family. When Guru Sahib reached Raikot state, the Muslim Chief Rai Kalha welcomed him and felt honored in offering his servicesto Guru Sahib as his guest for as long as he wanted to stay. Guru Ji spent a few days with Rai Kahla.
It was in Raikot that Guru Sahib got the most tragic news of the death of his two minor sons and his mother. The news was brought from Sarhind by Noora Mahi who deputed by Rai Kalha of the seva of Guru Sahib.
Guru Sahib during his stay asked Noora Mahi to serve him milk in Ganga Sagar (a vessle) having 288 holes which was part and parcel of his person belongings. Noora Mahi said that his buffalo did not give milk and even if it did, the milk will not stay in Ganga Sagar as it had holes in it. Guru Sahib told him to utter the name of God and start milking the buffalo. To the surprise and amazement of Noora Mahi, the buffalo gave milk and it did not leak out from the Ganga Sagar.

Before leaving Raikot, in recognition and appreciation of the services and hospitality extended by Rai Kalha, a Muslim Chief, who risked his own and his family’ lives, Guru Gobind Singh Ji presented Ganga Sagar, a sword and a Real to Rai Kalha as personal gifts.
Till 1947 the Ganga Sagar was displayed by Khan Bahadur Rai Inayat Khan for darshan by sangat who use to walk bare-footed from Gurdwara Tahliana Sahib in Raikot, Distt. Ludhian(Punjab) India.
The present owner of Ganga Sagar is Rai Azizzulah Khan (the 9th generation descendant of Rai Kalha III), a grandson of Khan Bahadur Rai Inayat Khan and the heir of the Rai family who have kept his sacred gift of Guru Gobin Singh Ji with great respect and care for almost 300 years.
