It is narrated from Hazrat Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) once went to a garden of Banu Najjar in Madinah Munawwarah. There, a sound was heard from a grave. The Prophet (peace and blessings be upon him) inquired about it and asked when the deceased had been buried in that grave. People replied, "O Messenger of Allah (peace and blessings be upon him)! This person was buried during the time of ignorance." The Prophet (peace and blessings be upon him) said, "If you people did not stop burying your dead, I would have prayed to Allah that He let you hear the punishment of the grave."
