All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
Shaving the beard and showing one’s ‘Awrah are evil matters. Therefore, if those husbands are as you described, then they are wrong, so one must advise them and remind them of Allaah. Some scholars and whoever might have an influence on them should advise them. Also, the wife should also advise her husband about these matters in a soft and gentle manner and she should supplicate Allaah to guide him and turn him into a righteous person.
On the other hand, a wife is not permitted to refuse if her husband calls her to bed unless she has a sound reason. Abu Hurayrah narrated that the Prophet said: ''When a man calls his wife to his bed (for intercourse) and she refuses, the angels will curse her till the morning." [Al-Bukhari and Muslim]
The fact that the husband commits those sins is not a sound reason for the wife to refuse his call to bed. Moreover, if a wife refuses, then this could be a reason for the husband to leave her and establish illicit relationships with other women and this leads to a greater evil and disadvantage as we clarified in Fatwa 88547.
Allaah Knows best.
