Musnad Abu Ya'la al-Mawsili 131:25

Muhammad ibn Isma'il ibn Abi Samina al-Basri narrated to us, Abdullah ibn Idris narrated to us, from al-Mukhtar ibn Fulful, from Anas ibn Malik, that the Messenger of Allah (may Allah bless him and grant him peace) was asked about a drink in Yemen called al-bit' and al-mizr. He said: "Whatever intoxicates is forbidden."
