Guru Nanak refused to be married according to the traditional rites since he was a reformer. The brahmins resisted and Mul Chand Chauna, would be father-in-law of the Guru, refused to marry his daughter to Nanak according to any other rites. A discussion took place between the brahmins and Guru Nanak, when the guru was given a seat near a crooked decaying mud-wall which was about to fall. The intention was to bury Nanak under the mud wall by giving it a little push. However an old lady informed Nanak who is said to have proclaimed 'This wall will not fall for centuries. The will of God shall prevail.' This wall has become the main attraction and it is shielded in glass and held in great reverence. Every year on the anniversary of Guru Nanak's marriage, a grand celebration is held here which is attended by thousands of devotees. During the festival, a gala procession is also arranged.
