It is narrated from Hazrat Umm Mubashir (may Allah be pleased with her) that once I was in a garden of Banu Najjar when the Prophet (peace and blessings of Allah be upon him) came to me. In that garden, there were also graves of some people who had died in the time of ignorance. The Prophet (peace and blessings of Allah be upon him) heard the sound of them being punished. The Prophet (peace and blessings of Allah be upon him) came out of the garden saying, "Seek refuge with Allah from the punishment of the grave." I asked, "O Messenger of Allah! Are they being punished in these graves?" The Prophet (peace and blessings of Allah be upon him) said, "Yes! And animals also hear this punishment."
