"When a woman give charity from her husband's house, she will have a reward, and her husband will have a similar reward, and the storekeeper will have a similar reward, without the reward of any of them detracting from the reward of the others in the slightest. The husband will be rewarded for what he earned and she will be rewarded for what she spent."  

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