"The Messenger of Allah passed by two graves and said: "They are being punished but they are not being punished for anything that was difficult to avoid. One of them used not to take care to avoid getting urine on his body or clothes, and the other used to walk about spreading gossip.' Then he took a fresh palm stalk and broke it in half, and planted one half on each grave. They said: 'O Messenger of Allah, why did not do that?' He said: 'May it be reduced for them so long as this does not dry out."'
