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.
First of all we advise you not to divorce your wife if she is a well-mannered and righteous woman. However, this does not affect the fact that the wife's disobedience to her husband is absolutely prohibited, though it has a remedy other than divorce as prescribed by the Sharee‘ah (Islamic law).
The Quran directs the husband whose wife disobeys him as follows: Allaah The Almighty Says (what means): {But those [wives] from whom you fear arrogance - [first] advise them; [then if they persist], forsake them in bed; and [finally], strike them. But if they obey you [once more], seek no means against them.} [Quran 4:34]. Thus, the husband should not resort to divorce until other solutions prescribed by the Sharee‘ah prove fruitless.
You should know that the woman is not financially responsible under the Sharee‘ah. Rather, this is the responsibility of the husband alone. However, there is no doubt that the Sharee‘ah has recommended the wife to help her husband in the financial expenses of life since this strengthens and maintains the relationship between the two spouses.
Consequently, if the woman helped her husband by spending some of her money as a debt then she is entitled to ask her husband to repay this debt at any time, but in case of being insolvent, she should wait until he finds money. On the other hand, if she helped him voluntarily, then she has no right to demand that her husband repay what she paid.
In any case, taking the husband's possessions from his house without his knowledge under the pretext that she had helped him features violation of others' possessions. It is impermissible for her to do so and she must return the things she took. Nevertheless, the husband has to repay what she gave him as a debt.
Allaah Knows best.
