It is narrated from Hazrat Abu Bakrah (may Allah be pleased with him) that once I was walking with the Prophet (peace and blessings be upon him), the Prophet (peace and blessings be upon him) was holding my hand, and there was a man on the left side as well. Suddenly, two graves appeared before us. The Prophet (peace and blessings be upon him) said, "These two men are being punished, and not for a major sin." He asked, "Who among you will bring me a branch?" We rushed, and I got ahead of them and brought a branch to the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) divided it into two parts and placed a piece on each grave and said, "As long as these remain fresh, their punishment will be lightened." And both of them are being punished only because of urine and backbiting.
