Musnad Ahmad 1153:2354

Ziyad ibn Abdullah narrated to us, he said: Mansur narrated to us, from Ibrahim, from al-Aswad, who said: I asked Aisha, "What did the Messenger of Allah, peace and blessings of Allah be upon him, forbid making nabidh (fermented drink) in?" She said: "He used to forbid the gourd (duba') and the pitch-coated vessel (muzaffat)." He said: I said, "What about the skin bag (sa'n)?" She said: "I only tell you what I heard, and I do not tell you what I did not hear."
