Praise be to Allaah.
Many shar‘i texts indicate that a woman’s obedience to her
husband takes precedence over her obedience to any other person, even her
own parents, so how about people other than them?
Shaykh al-Islam Ibn Taymiyah said: When a woman gets married,
her husband has more authority over her and her parents, and obedience to
her husband is more obligatory for her.
And he said: She does not have the right to go out of his
house except with his permission, whether her father or her mother or
someone tells her to do that, according to the consensus of the imams. End
quote. Majmoo‘ al-Fataawa, 32/361
So the husband's father and mother do not have any authority
over the wife and she is not obliged to obey them in what they tell her to
do, whether the husband approves of that or not. The most that can be said
concerning this matter is that she should respond to the wishes of her
husband's father and mother as much as is required to be kind and maintain a
good relationship, within the scope of her ability, but only in that which
will not conflict with obedience to her husband.
The scholars of the Standing Committee said: There is nothing
in Islam to indicate that the wife is obliged to help the husband's mother,
except within the bounds of kind treatment and as much as she is able, out
of kindness towards her husband and out of respect to her duties towards her
Fataawa al-Lajnah al-Daa’imah,
In that case, the role of the wise and smart husband is to
help his wife to avoid conflict with his family or confrontations with them;
he should take matters into his own hands from the outset and try to be kind
when reconciling between them and prevent division between them.
If it is possible to have separate accommodation for himself
and his wife, that is what he must do and that is better in order to
maintain good relationships and keep his life free of headaches.
