Sahih al-Bukhari, Volume 2, Book 24, Hadith 521 (USC-MSA) ⓘ

Narrated `Aisha: The Prophet 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 ‏" ‏‏.‏
