[Machine] Allah and His messenger have ruled that a woman is free to do whatever she wants as long as it is not something her husband dislikes. If her husband swears not to do something, then he is not allowed to do it. Ibn Abbas and Ibn Umar were asked about this and they said that if the woman wants to be freed, then she should be freed, and if she says, "I have nothing in the way of Allah," then she should give charity from her wealth. This is mentioned in this narration, and it has been narrated from Ibn Abbas and Ibn Umar that there is evidence for the permissibility of kafarah (expiation). Allah knows best. It has also been narrated from Ibn Abbas that there is another opinion on this matter.  

اللهِ وَجَارِيَتُهَا حُرَّةٌ إِنْ لَمْ يَفْعَلْ كَذَا وَكَذَا لِشَيْءٍ يَكْرَهُهُ زَوْجُهَا فَحَلَفَ زَوْجُهَا أَنْ لَا يَفْعَلَهُ فَسُئِلَ عَنْ ذَلِكَ ابْنُ عَبَّاسٍ وَابْنُ عُمَرَ ؓ فَقَالَا أَمَّا الْجَارِيَةُ فَتَعْتِقُ وَأَمَّا قَوْلُهَا مَالِي فِي سَبِيلِ اللهِ فَتَصَدَّقُ بِزَكَاةِ مَالِهَا كَذَا فِي هَذِهِ الرِّوَايَةِ وَقَدْ رُوِّينَا عَنِ ابْنِ عَبَّاسٍ وَابْنِ عُمَرَ ؓ مَا دَلَّ عَلَى جَوَازِ التَّكْفِيرِ وَاللهُ أَعْلَمُ وَرُوِيَ عَنِ ابْنِ عَبَّاسٍ ؓ فِي مَعْنَاهُ مَذْهَبٌ آخَرُ
