Hadith 8188

وَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " لَا تَصُومُ الْمَرْأَةُ وَبَعْلُهَا شَاهِدٌ إِلَّا بِإِذْنِهِ ، وَلَا تَأْذَنُ فِي بَيْتِهِ وَهُوَ شَاهِدٌ إِلَّا بِإِذْنِهِ ، وَمَا أَنْفَقَتْ مِنْ كَسْبِهِ عَنْ غَيْرِ أَمْرِهِ ، فَإِنَّ نِصْفَ أَجْرِهِ لَهُ " .
And the Prophet Muhammad (peace and blessings be upon him) said: No woman should observe a voluntary fast while her husband is present at home except with his permission, and no woman should allow anyone to enter her husband's house in his presence except with his permission, and whatever a woman spends from his wealth without his order, half of its reward is given to her husband.
