Jami` at-Tirmidhi 671
Aishah narrated that :
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."
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ عَمْرِو بْنِ مُرَّةَ، قَالَ سَمِعْتُ أَبَا وَائِلٍ، يُحَدِّثُ عَنْ عَائِشَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم 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 ‏"‏ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ ‏.‏
