Musnad Ahmad 788:189

Waki’ narrated to us, Shu’bah narrated to us, from Sa’id ibn Abi Burdah, from his father, from Abu Musa, who said: The Prophet, may Allah bless him and grant him peace, sent me and Mu’adh ibn Jabal to Yemen. I said: "O Messenger of Allah, there is a drink made in our land called 'al-mizr' from barley, and a drink called 'al-bit’' from honey." He said: "Every intoxicant is forbidden."
