When a woman spends (something as Sadaqa) out of the household of her husband without causing any damage, there is a reward for her and for him too like it for whatever he earned, and for her (for the wife) because of her spending (for the sake of Allah), and for the trustee also (there is a reward like it), without any reduction from their rewards.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَنْفَقَتِ الْمَرْأَةُ مِنْ بَيْتِ زَوْجِهَا غَيْرَ مُفْسِدَةٍ كَانَ لَهَا أَجْرُهَا وَلَهُ مِثْلُهُ بِمَا اكْتَسَبَ وَلَهَا بِمَا أَنْفَقَتْ وَلِلْخَازِنِ مِثْلُ ذَلِكَ مِنْ غَيْرِ أَنْ يَنْتَقِصَ مِنْ أُجُورِهِمْ شَيْئًا  

"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.”  

قَالَ رَسُولُ اللَّهِ ﷺ 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  

Messenger of Allah ﷺ said, "When a woman gives in charity some of the foodstuff (which she has in her house) without spoiling it, she will receive the reward for what she has spent, and her husband will receive the reward because of his earning, and the storekeeper will also have a reward similar to it. The reward of one will not decrease the reward of the others . " (Using translation from Bukhārī 1425)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِذَا أَنْفَقَتِ الْمَرْأَةُ مِنْ طَعَامِ بَيْتِهَا غَيْرَ مُفْسِدَةٍ كَانَ لَهَا أَجْرُهَا بِمَا أَنْفَقَتْ وَلِزَوْجِهَا أَجْرُهُ بِمَا اكْتَسَبَ وَلِلْخَازِنِ مِثْلُ ذَلِكَ لَا يَنْقُصُ بَعْضُهُمْ مِنْ أَجْرِ بَعْضٍ شَيْئًا  

"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.” (Using translation from Ibn Mājah 2294)   

قَالَ رَسُولُ اللهِ ﷺ «إِذَا أَنْفَقَتِ الْمَرْأَةُ مِنْ بَيْتِ زَوْجِهَا غَيْرَ مُفْسِدَةٍ كَانَ لَهَا أَجْرُهَا وَلَهُ مِثْلُهُ بِمَا كَسَبَ وَلَهَا بِمَا أَنْفَقَتْ وَلِلْخَازِنِ مِثْلُ ذَلِكَ مِنْ غَيْرِ أَنْ يُنْتَقَصَ مِنْ أُجُورِهِمْ شَيْءٌ» وَقَفَهُ حَبِيبُ بْنُ أَبِي ثَابِتٍ  

A’ishah reported The Messenger of Allah ﷺ as saying When a woman gives (some of the property) from her husband’s house, not wasting it, she will have her reward for what she has spent, and her husband will have his for what he earned. The said applies to a trustee. In no respect does the one diminish the reward of the other. (Using translation from Abū Dāʾūd 1685)   

"إذَا أَنفقت المرأةُ من بيتِ زوجها غيرَ مُفسدةٍ كان لها أجرُها بِما أنفقتْ -ولزوجِها أجرُه بما كَسَب- وللخازن مثل ذلك- لا ينقصُ بعضُهم من أجرِ بعضٍ شيئًا" .
