Sahih Muslim 1023
Sahih Muslim · Book 12: The Book of Zakat · The reward of the Trustworthy Trustee, and if a woman gives charity from her husband's house without causing any damage, with his explicit or implicit permission
Abu Musa reported Allah's Apostle (ﷺ) as saying:
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، وَأَبُو عَامِرٍ الأَشْعَرِيُّ وَابْنُ نُمَيْرٍ وَأَبُو كُرَيْبٍ كُلُّهُمْ عَنْ أَبِي أُسَامَةَ ، - قَالَ أَبُو عَامِرٍ حَدَّثَنَا أَبُو أُسَامَةَ، - حَدَّثَنَا بُرَيْدٌ ، عَنْ جَدِّهِ أَبِي بُرْدَةَ ، عَنْ أَبِي مُوسَى ، عَنِ النَّبِيِّ صلى الله عليه وسلم 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 " .
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.
