Sahih al-Bukhari, Book 24, Hadith 43 (In-Book) ⓘ

Narrate Aisha: The Prophet 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 ‏" ‏‏.‏
