Messenger of Allah ﷺ said, "It is not lawful for a lady to fast (Nawafil) without the permission of her husband when he is at home; and she should not allow anyone to enter his house except with his permission; and if she spends of his wealth (on charitable purposes) without being ordered by him, he will get half of the reward."

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَحِلُّ لِلْمَرْأَةِ أَنْ تَصُومَ وَزَوْجُهَا شَاهِدٌ إِلاَّ بِإِذْنِهِ وَلاَ تَأْذَنَ فِي بَيْتِهِ إِلاَّ بِإِذْنِهِ وَمَا أَنْفَقَتْ مِنْ نَفَقَةٍ عَنْ غَيْرِ أَمْرِهِ فَإِنَّهُ يُؤَدَّى إِلَيْهِ شَطْرُهُ وَرَوَاهُ أَبُو الزِّنَادِ أَيْضًا عَنْ مُوسَى عَنْ أَبِيهِ عَنْ أَبِي هُرَيْرَةَ فِي الصَّوْمِ

These are some of the a hadith of Muhammad. the Messenger of Allah ﷺ, transmitted to us on the authority of Abu Huraira. So he narrated one hadith out of them (as this): The Messenger of Allah ﷺ said: No woman should observe fast when her spouse is present (in the house) but with his permission. And she should not admit any (mahram) in his house, while he (her husband) is present, but with his permission. And whatever she spends from his earnings without his sanction, for him is half the reward.

عَنْ مُحَمَّدٍ رَسُولِ اللَّهِ ﷺ فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ ﷺ لاَ تَصُمِ الْمَرْأَةُ وَبَعْلُهَا شَاهِدٌ إِلاَّ بِإِذْنِهِ وَلاَ تَأْذَنْ فِي بَيْتِهِ وَهُوَ شَاهِدٌ إِلاَّ بِإِذْنِهِ وَمَا أَنْفَقَتْ مِنْ كَسْبِهِ مِنْ غَيْرِ أَمْرِهِ فَإِنَّ نِصْفَ أَجْرِهِ لَهُ

The Prophet ﷺ said, "A woman should not fast (optional fasts) except with her husband's permission if he is at home (staying with her). (Using translation from Bukhārī 5192)

وَقَالَ رَسُولُ اللهِ ﷺ 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

"لَا تَصُم المَرْأةُ وَبَعْلُها شَاهِدٌ إلا بِإِذْنِهِ غَيرَ رَمَضَانَ، ولَا تَأذَنْ فِي بَيتِهِ وهُو شَاهِدٌ إلا بِإِذْنِهِ، وَمَا أَنْفَقَتْ مِنْ كَسْبِهِ مِنْ غَيرِ أمْرِهِ فَإنَّ نِصْفَ أَجْرِهِ لَهُ".
