Musnad Ahmad 32:1993

Abu Dawud narrated to us, Shu'bah informed us, from Qatadah, who said: I asked Anas about the *nabidh* (fermented drink) of the earthen jar. He said: "I did not hear anything from the Messenger of Allah, may Allah bless him and grant him peace, regarding it." He said: "And Anas used to dislike it."
