Musnad Ahmad 28:71

Yazid narrated to us, Faraj ibn Fudalah informed us, from Ibrahim ibn Abd al-Rahman ibn Rafi’, 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), Maysir (gambling), Mizr (a fermented drink made from barley or corn), Kūbah (a drum), and Qunayn." And he added for me: "The Witr prayer." Yazid said: "The Qunayn is the Barābit (lutes/stringed instruments)."
