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.
A husband should not sleep outside his house without a need to do so especially if this leads to neglecting one of his obligations, like the right of the wife to be satisfied sexually or emotionally.
Whoever does so should be advised in a wise manner and he should be reminded about his responsibility towards his wife and children and their need for his care. His wife should also be advised to be patient with him and beautify herself for him and prepare an environment for his rest at home so that he will not need to go out and look for happiness and rest outside his home.
For more benefit, please refer to Fatwa 83962.
Allaah Knows best.
