The Messenger of Allah passed by one of the gardens of Makkah or Al-Madinah and heard the sound of two men being tormented in their graves. The Messenger of Allah said: "They are being punished but they are not being punished for anything that was difficult to avoid." Then he said: "Indeed, one of them used not to take care to avoid getting urine on his body or clothes, and the other used to walk around spreading gossip." They he called for a palm stalk which he broke in two and placed a piece of it on each grave. It was said to him: "O Messenger of Allah, why did you do that?" He said: "May it be reduced for them so long as this does not dry out" or: "until this dries out."

← Previous Hadith "Two of the old Jewish women of Al-Madinah came to me and said: 'The people of the graves are tormented in their graves.' But I did not believe them, and I did not believe them, and I did not want to believe them. They left and the Messenger of Allah entered upon me, and I said: 'O Messenger of Allah, two of the old Jewish women of Al-Madinah said that the people of the graves are tormented in their graves.' He said: 'They spoke the truth. They are tormented in a manner that all the animals can hear.' And I never saw him offer any Salah but he sought refuge with Allah from the torment of the grave."

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."'
