Jami` at-Tirmidhi Book 43, Hadith 74
that the Prophet (ﷺ) said: "Whoever believes in Allah and the Last Day, then he is not to let his wife enter the Hammam, and whoever believes in Allah and the Last Day, then he is not to enter the Hammam without an Izar. And whoever believes in Allah and the Last Day, then he is not to sit at a spread in which Khamr is circulated."
from Laith, from Nafi, from Ibn 'Umar that the Messenger of Allah (ﷺ) said: "Beware of nakedness! For indeed there are with you, those who do not part from you except at the place of defecation, and when a man goes into his wife. So be shy of them and honor them."
from 'Aishah, that the Prophet (ﷺ) prohibitied the men and women from the Hammamat (plural of Hammam), then he permitted it for the men in Izar."
