Musannaf Ibn Abi Shayba 13:2534

Abu Bakr narrated to us, he said: Waki’ narrated to us, he said: Isma’il bin Abi Khalid narrated to us, from Hakim bin Jabir, from ‘Ubadah bin as-Samit, he said: I heard the Prophet, peace and blessings of Allah be upon him, saying: "Gold for gold, weight for weight; and silver for silver, weight for weight," until he reached salt. ‘Ubadah said: "By Allah, I do not care if I am not in a land where Mu’awiyah is."
