Musnad Abu Ya'la al-Mawsili 116:27

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