Musnad Ahmad 1086:5

Sufyan narrated to us, from al-Zuhri, from Haram ibn Sa'd ibn Muhayyisah, that Muhayyisah asked the Prophet, peace and blessings of Allah be upon him, about the earnings of a cupper of his. He forbade him from it, but he continued to speak to him until he said: "Feed it to your water-carrying camel and feed it to your slaves."
