Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings be upon him) say: "The expiation for a gathering is that a person, after getting up, recites:
'Subhanaka Allahumma wa bihamdika, la ilaha illa anta, astaghfiruka wa atubu ilayk' (Glory be to You, O Allah, and praise is Yours; there is no god but You; I seek Your forgiveness and turn to You in repentance)."
Tabarani recorded it in al-Mu'jam al-Awsat and al-Mu'jam al-Kabir, but al-Mu'jam al-Kabir does not have the words "after getting up". The chains of both reports contain a narrator, Ata' bin al-Sa'ib, who suffered from ikhtilat (deterioration of memory).
