Musnad Ahmad 28:88

Abu al-Nadr narrated to us, al-Faraj narrated to us, Ibrahim ibn Abd al-Rahman ibn Rafi’ narrated to us, from his father, from Abdullah ibn Amr, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Indeed, Allah has forbidden for my nation: Khamr (intoxicants), al-Maysir (gambling), al-Mizr (a fermented beverage made from corn or barley), al-Qunayn (a type of musical instrument or vessel used for drinking), and al-Kubah (a drum). And He added for me the Witr prayer."
