He Made it Conditional Upon Her That She Has Nothing Except Her Living Expenses

Question :

A woman has no interest except in transmitting what is said in her house to her family and to her neighbors, disclosing the secrets of her family and her husband. So he gave her the choice of remaining with him, without anything except her living expenses, or to be parted from him, so she chose to stay. Are there any other obligations upon him regarding her, after this condition?

Answer:

A The action of this woman is forbidden, because it is not permissible for a woman to reveal anything of the secrets of her family neither to her relatives nor to anyone else - because they are a trust which she is obliged to protect; and Allah, Most High has said:
"Therefore the righteous women are devoutly obedient (to Alläh and to their husbands), and guard in the husband's absence what Allah orders them to guard (e.g. their chastity and their husband's property).

And if the man agreed with this woman that she should remain with him without anything except her living expenses, and she accepted that, then she has nothing except those expenses, according to the words of the Prophet:
"The Muslims must fulfill their conditions, unless it is a condition which legalizes that which is unlawful or declares unlawful that which is lawful."

and the words of him:
"Any condition which is not in the Book of Allah is invalid, even if there be a hundred conditions."
