Uqbah bin Sayyar narrates from a man who said: We were sitting with Abu Hurayrah (may Allah be pleased with him) when Marwan came and stood over him and said: "O Abu Hurayrah, you keep narrating hadiths that we do not know." Then he went away, then came back and said: "O Abu Hurayrah, how is the funeral prayer over the deceased?" He said: "Along with what you said just now?" He said: "Yes." So he said: We used to say: 'Allahumma anta rabbuha' (O Allah, You are her Lord).
