Musnad Ahmad 1086:0

Narrated to us by Yahya ibn Sa’id, from Sufyan, who said: Narrated to us Habib ibn Abi Thabit, from Maymun ibn Abi Shabib, from Muhayyisah ibn Mas’ud, that he went to the Messenger of Allah (ﷺ) to ask him about the earnings of a cupper. The Prophet (ﷺ) forbade him from it and scolded him. He said: "O Messenger of Allah, it is only the food of my servant." He said: "Feed it to the camels." He said: "And the food of my camel." He said: "Feed it to the camels." He said: "And the food of my camel." He said: "Feed it to the camels." He said: "O Messenger of Allah, it is only the food of my servant." He said: "Then feed it to the camels, or feed it to the dogs."
