It is narrated from Ata bin Yasar (may Allah have mercy on him) that Muawiyah bin Abi Sufyan (may Allah be pleased with him) once sold a gold or silver vessel for more than its weight. So Abu Darda (may Allah be pleased with him) said to him, "I heard the Prophet (ﷺ) forbidding this." Muawiyah (may Allah be pleased with him) said, "In my opinion, there is nothing wrong with it." So Abu Darda (may Allah be pleased with him) said, "Who will excuse me regarding Muawiyah? I narrate to him the hadith of the Messenger of Allah (ﷺ), and he tells me his own opinion. I will not stay in the land in which (O Muawiyah!) you reside."
