"During a sermon of his in the year of the Farewell Hajj, I heard the Messenger of Allah say: 'A woman is not to spend anything from her husbands house without her husband's permission.' They said: 'O Messenger of Allah! What about food?' He said: 'That is our most virtuous wealth.'"  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ فِي خُطْبَتِهِ عَامَ حَجَّةِ الْوَدَاعِ يَقُولُ لاَ تُنْفِقُ امْرَأَةٌ شَيْئًا مِنْ بَيْتِ زَوْجِهَا إِلاَّ بِإِذْنِ زَوْجِهَا قِيلَ يَا رَسُولَ اللَّهِ وَلاَ الطَّعَامُ قَالَ ذَاكَ أَفْضَلُ أَمْوَالِنَا وَفِي الْبَابِ عَنْ سَعْدِ بْنِ أَبِي وَقَّاصٍ وَأَسْمَاءَ بِنْتِ أَبِي بَكْرٍ وَأَبِي هُرَيْرَةَ وَعَبْدِ اللَّهِ بْنِ عَمْرٍو وَعَائِشَةَ  

the Prophet said: "When a woman gives in charity from her husband's house, she will get the reward for it, and for her husband is the same as that, and for the trustee is the same as that. The reward of each them will not be decreased at all by the reward of the other, for him is what he earned, and for her is what she spent."  

عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ إِذَا تَصَدَّقَتِ الْمَرْأَةُ مِنْ بَيْتِ زَوْجِهَا كَانَ لَهَا بِهِ أَجْرٌ وَلِلزَّوْجِ مِثْلُ ذَلِكَ وَلِلْخَازِنِ مِثْلُ ذَلِكَ وَلاَ يَنْقُصُ كُلُّ وَاحِدٍ مِنْهُمْ مِنْ أَجْرِ صَاحِبِهِ شَيْئًا لَهُ بِمَا كَسَبَ وَلَهَا بِمَا أَنْفَقَتْ  

the Messenger of Allah said: "When a woman gives from her husband's home, with a good heart, not to spoil it, then she will get a reward similar to his, for her is the good she intended - and the same is for the trustee."  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَعْطَتِ الْمَرْأَةُ مِنْ بَيْتِ زَوْجِهَا بِطِيبِ نَفْسٍ غَيْرَ مُفْسِدَةٍ كَانَ لَهَا مِثْلُ أَجْرِهِ لَهَا مَا نَوَتْ حَسَنًا وَلِلْخَازِنِ مِثْلُ ذَلِكَ
