Musnad Abu Ya'la al-Mawsili 108:158

Abu Bakr narrated to us, Mus'ab narrated to us, Hasan bin Salih narrated to us, from Layth, from Tawus, from Jabir, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever believes in Allah and the Last Day, let him not enter the bathhouse without an izar (waist wrapper). And whoever believes in Allah and the Last Day, let him not allow his wife to enter the bathhouse. And whoever believes in Allah and the Last Day, let him not eat at a table upon which wine is being drunk."
