What is the status of the hadith telling people to seek help from the occupants of graves when facing difficult matters?

Summary

The narration instructing people to seek help from the occupants of graves when beset by difficult affairs is judged fabricated by hadith scholars. It is not found in any authoritative hadith collection, and Ibn Taimiyyah cited it in Majmuʻ al-Fatawa as a lie attributed to the Prophet. It therefore must not be spread or acted upon, and authors of religious books should not use it as evidence.

Written in our own words from the original fatwa — check the source before acting on it.
