´It was narrated that 'Ubadah bin As-Samit said:` "I heard the Messenger of Allah say: 'Gold, equal amount."' (One of the narrators) Yaqub did not mention: "Equal amount." Muawiyah said: "This does not mean anything." 'Ubadah said; "By Allah I do not care if I am in a land where Muawiyah is not present. I bear witness that I heard the Messenger of Allah say that."
