The Messenger of Allah ﷺ said, "The lands of the non-Arabs will be conquered for you, and you will find in them houses called bathhouses. Some men must not enter them except wearing waist-wraps, and forbid women from entering them except for one who is ill or recovering from childbirth."
حدثنا أحمد بن يونس حدثنا زهير حدثنا عبد الرحمن بن زياد بن أنعم عن عبد الرحمن بن رافع
أن رسول الله ﷺ قال إنها ستفتح لكم أرض العجم وستجدون فيها بيوتا يقال لها الحمامات فلا يدخلنها الرجال إلا بالأزر وامنعوها النساء إلا مريضة أو نفساء
[Its chain of transmission is daif] Ibn Majah collected it in the chapter on manners, the section on entering the public bath, hadith 3748, from the hadith of Abdul-Rahman bin Ziyad Afriqi, and he is daif, as previously noted at hadith 62 and 270. Abdul-Rahman bin Rafi is also daif.
