"Peace having been made with the Marathas, Najib-ud-daulah had retired to Wazirabad, 10 kilometres from the city situated on the banks of the Jamuna. The Maratha camp was also located near by. Raghunathrao used to bathe in the Jamuna every morning. His way lay near the camp of Najib-ud-daulah. Cows were slaughtered daily in Najib’s camp. Their blood, bones and skins were lying near the route followed by Raghunathrao and other Brahmans who also bathed there. Raghunathrao felt incensed. He asked Malhar to prevail upon Najib to stop cow-slaughter till he was encamped on the Jamuna. Najib replied: “This is a religious matter and I will never abandon it.”"
