Sayyiduna Abdullah bin Mughaffal (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Whenever some people gather in a gathering and rise without remembering Allah Almighty, that gathering will be a cause of regret for them on the Day of Resurrection."
Tabarani recorded it in al-Mu'jam al-Awsat and al-Mu'jam al-Kabir, and the narrators of both are the narrators of the Sahih.
