Jami` at-Tirmidhi Book 43, Hadith 73
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."
"I heard Sa'eed bin Musayyab saying: 'Indeed Allah is Tayyib (good) and he loves Tayyib (what is good), and He is Nazif (clean) and He loves cleanliness, He is Karim (kind) and He loves kindness, He is Jawad (generous) and He loves generosity. So clean' - I think he said - 'your courtyards, and do not resemble the Jews.'" He said: "I mentioned that to Muhajir bin Mismar, and he said: "Amir bin Sa'd narrated it to me from his father from the Prophet (ﷺ), similarly, except that he did not say: "Clean your courtyards."
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."
