Guru Nanak Dev's father, himself a man of the world and a revenue accountant of Rai Bular, wanted his son to settle in business. He once gave the boy money and sent him, with one Bhai Bala to Chuharkana market to purchase merchandise for setting up a shop. "Make good, profitable bargain", the father advised. Chuharkana was about 20 kilometres Northeast of Talwandi Rai Bhoi (it is now a railway station on the Sheikhupura-Faisalabad section of Pakistan Railways).
A little short of their destination, Nanak and Bala came across group of sadhus, naked and hungry. The former at once decided to feed them, and despite Bala's advice not to do so, bought provisions from Chuharkana and served them a hearty meal.
On his return home empty handed, Guru Nanak's father rebuked him for squandering his precious cash, but he calmly answered, "you had wanted me to make 'Khara Saudha' (Lit. real bargain); I could not think of a better and more genuine one than the one I have made." The Gurdwara established during the Sikh Rule on the spot where the sadhus were entertained came to be called Sacah Soda. Now called Gurdwara Sacha Sauda (Lit. true bargain), it stands between the mandi (market) and the town of Chuharkana. Its domed sanctum in the middle of a square hall stands in a fort-like enclosure. Khalsa Divan Bar, under the leadership of Jathedar Kartar Singh Jhabbar, liberated the Gurdwara from the centuries-old control of Udasi mahants on December 30, 1920.
