Musnad Abu Ya'la al-Mawsili 245:10

Uthman ibn Abi Shaybah narrated to us, Abu Bakr ibn Ayyash narrated to us, from Asim ibn Abi al-Najud, from Abu Salih, from Muawiyah, who said: I heard the Prophet, peace and blessings of Allah be upon him, saying: "Whoever drinks wine, then flog him. If he returns (to it), then flog him. If he returns (to it), then kill him."
