Savittha, staying in the Ghositārāma at Kosambī, asks Musīla about the Paticca-Samuppāda, and discovers from the answers given that Musīla is an arahant. Savittha asks Nārada the same questions at the latter's own request and receives the same answers; but Nārada declares that he is not an arahant. Ananda is also present and joins in the discussion. S.ii.115f.
