Narrated `Aisha:

Allah's Messenger (ﷺ) said, "When a woman gives in charity from her husband's meals without wasting the property of her husband, she will get a reward for it, and her husband too will get a reward for what he earned and the storekeeper will have the reward likewise."

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا جَرِيرٌ، عَنِ الأَعْمَشِ، عَنْ أَبِي وَائِلٍ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏

‏ إِذَا تَصَدَّقَتِ الْمَرْأَةُ مِنْ طَعَامِ زَوْجِهَا غَيْرَ مُفْسِدَةٍ كَانَ لَهَا أَجْرُهَا، وَلِزَوْجِهَا بِمَا كَسَبَ، وَلِلْخَازِنِ مِثْلُ ذَلِكَ ‏

‏‏.‏
