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.
If a wife is under her husband’s guardianship and he sufficiently spends on her, then she is obliged to seek his permission if she wants to go out, whether this is to learn computer, or learn cooking or for walking around with her family. If she goes out without his permission then she is sinful but we are not aware of any specific punishment for this; for more benefit, please refer to Fatwa 83157.
You should know that divorce is permissible even if it took place without any reason, but divorce is disliked if it takes place without a need.
However, if a wife is disobedient, there are some Islamic steps to take in order to discipline her, so one should not hasten to divorce before exhausting all these means; for more benefit, please refer to Fatwa 85402. It could be that the solution is not in returning the wife to her parents’ house; rather, this may worsen the situation.
Therefore, we advise you to be patient with your wife and try to rectify her by following these Islamic means. If she improves, all praise be to Allaah, but if she persists in her behaviour, then you may divorce her especially because she has a bad conduct as you mentioned.
On the other hand, the Islamic (permissible) divorce is when a husband divorces his wife when she is pregnant or in a period of purity during which he did not have sexual intercourse with her and it is desirable to have witnesses for this kind of divorce.
You may divorce her without any compensation or you may refuse to divorce her until she pays you compensation because she is disobedient; for more benefit, please refer to Fatwa 82735.
Finally, it should be noted that marital life should be based on mutual respect between the husband and wife because this is a means for the continuity of the marital relationship between them.
For more benefit on the duties of spouses towards each other, please refer to Fatwa 85308.
Allaah Knows best.
