Narrated from Sayyiduna Ubadah bin Samit (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Gold for gold and silver for silver are equal in exchange. Even salt was specifically mentioned here. Sayyiduna Muawiyah (may Allah be pleased with him) said: There is no importance to what Sayyiduna Ubadah (may Allah be pleased with him) says, (this is not a Prophetic hadith). Upon hearing this, Sayyiduna Ubadah (may Allah be pleased with him) said: I do not care that wherever I am, Sayyiduna Muawiyah (may Allah be pleased with him) is also there; I bear witness that I heard the Messenger of Allah (peace and blessings be upon him) stating this.
