Sunan Ibn Majah, Volume 3, Book 12, Hadith 2294 (DarusSalam) ⓘ
It was narrated from 'Aishah that the Messenger of Allah said: "When a woman spends" and my father said: - "When a woman feeds (the poor) from her husband's house, without spending too much, she will have her reward, and he will be rewarded likewise because he earned it, and she will be rewarded for what she spent. The same applies to the storekeeper, without anything being detracted from their rewards.”
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا أَبِي وَأَبُو مُعَاوِيَةَ عَنِ الأَعْمَشِ، عَنْ أَبِي وَائِلٍ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، قَالَتْ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " إِذَا أَنْفَقَتِ الْمَرْأَةُ - وَقَالَ أَبِي فِي حَدِيثِهِ إِذَا أَطْعَمَتِ الْمَرْأَةُ - مِنْ بَيْتِ زَوْجِهَا غَيْرَ مُفْسِدَةٍ كَانَ لَهَا أَجْرُهَا وَلَهُ مِثْلُهُ بِمَا اكْتَسَبَ وَلَهَا بِمَا أَنْفَقَتْ وَلِلْخَازِنِ مِثْلُ ذَلِكَ مِنْ غَيْرِ أَنْ يَنْقُصَ مِنْ أُجُوِرِهِمْ شَيْئًا " .
