Musnad Ahmad 27:1339

Muhammad ibn Ubayd narrated to us, Ubayd Allah ibn Umar narrated to us, from Nafi, from Ibn Umar, who said: The Messenger of Allah (peace and blessings of Allah be upon him) addressed the people one day. I came when he had finished, so I asked the people: "What did he say?" They said: "He forbade making nabidh (a fermented drink) in green-glazed jars (al-muzaffat) and gourds (al-qara)."
