It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that she said: "The Prophet (peace and blessings be upon him) passed by two graves whose occupants were being punished, and he (peace and blessings be upon him) said: 'These two are being punished, and they are not being punished for something that was difficult (to avoid). One of them did not guard himself against (splashes of) urine, while the other used to go about spreading tales.' Then he (peace and blessings be upon him) called for a fresh palm stalk, broke it, placed one part on each of the two graves and said: 'It is hoped that their punishment will be lightened as long as these stalks do not dry out.'"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Mansur (may Allah have mercy on him) except Abidah bin Humayd (may Allah have mercy on him), and Ali bin Ja'far al-Ahmar (may Allah have mercy on him) is alone in narrating it."
