Sahih al-Bukhari 1441
Narrated `Aisha:
The Prophet (ﷺ) said, "When a woman gives in charity from her house meals in Allah's Cause without 
spoiling her husband's property, she will get a reward for it, and her husband will also get the reward 
for his earnings and the storekeeper will get a reward likewise."
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ شَقِيقٍ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏
"‏ إِذَا أَنْفَقَتِ الْمَرْأَةُ مِنْ طَعَامِ بَيْتِهَا غَيْرَ مُفْسِدَةٍ فَلَهَا أَجْرُهَا، وَلِلزَّوْجِ بِمَا اكْتَسَبَ، وَلِلْخَازِنِ مِثْلُ ذَلِكَ ‏"‏‏.‏
