Sahih al-Bukhari 1440
Narrate Aisha:
The Prophet (ﷺ) said, "If a woman gives in charity from her husband's house .." The Prophet (p.b.u.h) also 
said, "If a lady gives meals (in charity) from her husband's house without spoiling her husband's 
property, she will get a reward and her husband will also get a reward likewise. The husband will get a 
reward because of his earnings and the woman because of her spending."
حَدَّثَنَا عُمَرُ بْنُ حَفْصٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا الأَعْمَشُ، عَنْ شَقِيقٍ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏
"‏ إِذَا أَطْعَمَتِ الْمَرْأَةُ مِنْ بَيْتِ زَوْجِهَا غَيْرَ مُفْسِدَةٍ، لَهَا أَجْرُهَا، وَلَهُ مِثْلُهُ، وَلِلْخَازِنِ مِثْلُ ذَلِكَ، لَهُ بِمَا اكْتَسَبَ، وَلَهَا بِمَا أَنْفَقَتْ ‏"‏‏.‏
