Ibn Battah (d.380H) – rahimahullaah – said whilst speaking about the prohibited matters in the Islaamic Legislation,
“And that he obeys his wife in permitting her to go to the ’urusaat and niyaahaat.” 
Shaykh Muhammad Ibn Haadee comments by saying,
“Meaning that it is not befitting that the man obeys his wife in allowing her to go out to the ’urusaat, and what is meant here is the place where the food of the waleemah (wedding feast) is eaten. The reason for prohibiting the women from going to this place is because of the evils that are found and occur in these places. Thus the man would take part in leading his family to evils, whereas he has been commanded to preserve them and guard them and keep them away from evil things.
As for the author’s statement, ‘niyaahaat,’ what is meant here is crying over the deceased in a loud voice. The women from the times of al-Jaahilyyah (pre-Islaamic times of ignorance) used to gather and scream, cry, and place dirt upon the top of their heads out of grieving for the deceased. This is what is known as ‘nawh,’ (taken from niyaahah), and it is to cry in a loud voice over the deceased, and this is from the customs of al-Jaahiliyyah, so it is not permissible. So therefore it is not permissible for the husband to let his wife go to the places where this niyaahah takes place. This affair is something that will remain within the Ummah of Muhammad (sallallaahu ’alayhi wa sallam) for indeed he (’alayhis-salaam) informed about this in his statement,
“There are four things from the affairs of al-Jaahiliyyah which my nation will not leave off…” He mentioned from those things niyaahah (wailing over the deceased). 
So niyaahah is an evil affair from the affairs of al-Jaahiliyyah, and the Prophet (sallallaahu ’alayhi wa sallam) informed us about the affair of the woman who wails over the deceased. She will be brought forth on the Day of Resurrection, if she does not repent, wearing a cloak of scabies, and Allaah’s refuge is sought from this. This proves the great evil of this action of hers, its loathsomeness and wickedness. So it is not permissible for a person to let his wife attend the places which in them are the customs of the people of al-Jaahiliyyah, and the author will speak about niyaahah specifically later on in the book (no. 440).”
The author (Ibn Battah) says,
“Likewise, the hammaamaat.”
Shaykh Muhammad Ibn Haadee comments,
“He means, also it is not permissible that a husband lets his wife go to the hammaamaat. That which is intended by this are the places specifically used for bathing and washing up, and it is not intended here the places used for one to relieve themselves, which many people intend today when the word hammaamaat is used.
So that which is meant by ‘hamaamaat,’ here, is almost what we know today as spas or Turkish baths. In the old days, these steam houses used to exist in the lands of Shaam (Syria, Jordan, Palestine) and its surrounding areas. This is because they are lands which have cold weather and the people are in need of bathing themselves, and in the summer this affair becomes worse. So they go to these hammaamaat which are prepared for the purpose of bathing and they find therein relief with the least discomfort from otherwise which they would have found hardship.
So the Prophet (sallallaahu ’alayhi wa sallam) also prohibited this as is found in the hadeeth of Jaabir (radiyallaahu ’anhumaa) that the Prophet (sallallaahu ’alayhi wa sallam) said,
“Whoever from you believes in Allah and the last day, do not let his wife enter the bath houses (hammaamaat).” 
Also it has been reported upon Aboo Maleeh al-Hudhalee (rahimahullaah) that some women from Homs (a city in Syria) or from Shaam entered upon ’Aa‘ishah (radiyallaahu ’anhaa), so she said to them,
‘Are you those whose women enter the bath houses? I heard the Prophet (sallallaahu ’alayhi wa sallam) say, ‘There is no woman who takes off her clothes in other than the house of her husband except that she will remove the veil between her and between her Lord.” 
The point of benefit is that the Muslim women must guard themselves, and it is incumbent that they leave off going to the likes of these places. This is because these places are open to the public, so perhaps a man may steal a look at her whilst she is unaware. So it is incumbent upon the believing woman to guard herself from going to the likes of this place and likewise the man if it involves private areas being exposed.
Unfortunately, many people today have disregard for this matter and as you have heard, these are narrations from the Prophet (sallallaahu ’alayhi wa sallam).”
