Both were honest men and had deep faith in the Guru. They made an ardas, supplicating the Guru that their honour be vindicated. It is said that Guru Arjan was on that day in a congregation at Amritsar. A Sikh made an offering of five pice. The Guru took up the coins and, weighing them on his palm, began shifting them from one hand to the other and back again. The sangat was perplexed. Offerings, precious as well as humble, had always been made to the Guru, but he had hardly ever touched them.
Soon. however, Guru Arjan dropped the coins and smiled. Asked by the Sikhs to reveal the mystery, the Guru said that he was countervailing the weights of his innocent Sikhs in trouble. Meanwhile, the weights of Bhai Bhana`s store had been tested and found to be correct. Bhai Kahn Singh Nabha, Gurushabad Ratnakar Mahan Kosh and Bhai Santokh Singh, Sri Gur Pratap Suraj Granth, also mention this anecdote, but in reference to one Bhai Katara and not to Bhai Bhana Mallan and Bhai Rekh Rao.
