Hadith 3125
Sayyida Umm Mubashir (may Allah be pleased with her) narrates: The Prophet Muhammad (peace be upon him) came to me while I was in a garden of Banu Najjar in which there were some graves of theirs. The Prophet (peace be upon him) was saying: Seek refuge with Allah from the punishment of the grave. I asked: O Messenger of Allah (peace be upon him)! Will there be punishment in the grave? The Prophet (peace be upon him) said: Yes, people are punished in their graves, which even animals hear.
