Sayyiduna Jabir (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Whoever has a hadith reach him on my authority and denies it has denied three: Allah Almighty, His Messenger, and the one who narrated that hadith."
Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, Mahfuz bin Miswar, whom Ibn Abi Hatim mentioned, but he did not mention any criticism (jarh) or commendation (ta'dil) of him.
