The honest Muslim trustee who spends (sometimes he said" who gives" ) what he is commanded to do and he gives that in full with his heart overflowing with cheerfulness and he gives it to one to whom he is ordered, he is one of the givers of charity.  

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ الْخَازِنَ الْمُسْلِمَ الأَمِينَ الَّذِي يُنْفِذُ وَرُبَّمَا قَالَ يُعْطِي مَا أُمِرَ بِهِ فَيُعْطِيهِ كَامِلاً مُوَفَّرًا طَيِّبَةً بِهِ نَفْسُهُ فَيَدْفَعُهُ إِلَى الَّذِي أُمِرَ لَهُ بِهِ أَحَدُ الْمُتَصَدِّقَيْنِ  

When a woman gives in charity some of the food in her house, without causing any damage, there is reward for her for whatever she has given, and a reward for her husband for what he earned. The same applies to the trustee. In no respect does the one diminish the reward of the other.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَنْفَقَتِ الْمَرْأَةُ مِنْ طَعَامِ بَيْتِهَا غَيْرَ مُفْسِدَةٍ كَانَ لَهَا أَجْرُهَا بِمَا أَنْفَقَتْ وَلِزَوْجِهَا أَجْرُهُ بِمَا كَسَبَ وَلِلْخَازِنِ مِثْلُ ذَلِكَ لاَ يَنْقُصُ بَعْضُهُمْ أَجْرَ بَعْضٍ شَيْئًا  

" from the food of her husband".  

وَقَالَ مِنْ طَعَامِ زَوْجِهَا  

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  

This hadith has been narrated by A'mash with the same chain of transmitters.  

عَنِ الأَعْمَشِ بِهَذَا الإِسْنَادِ نَحْوَهُ
