It is narrated from Hazrat Anas (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) was riding his white mule and passed by a garden of Banu Najjar in Madinah Munawwarah. There, punishment was being inflicted in a grave, so the mule shied. The Prophet (peace and blessings be upon him) said: "If you people would not stop burying your dead, I would have prayed to Allah to let you hear the sound of the punishment of the grave."
