The Reward Of The Storekeeper If He Gives Charity With His Master's Permission
Sunan an-Nasai
أَخْبَرَنِي عَبْدُ اللَّهِ بْنُ الْهَيْثَمِ بْنِ عُثْمَانَ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ بُرَيْدِ بْنِ أَبِي بُرْدَةَ، عَنْ جَدِّهِ، عَنْ أَبِي مُوسَى، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " الْمُؤْمِنُ لِلْمُؤْمِنِ كَالْبُنْيَانِ يَشُدُّ بَعْضُهُ بَعْضًا " . وَقَالَ " الْخَازِنُ الأَمِينُ الَّذِي يُعْطِي مَا أُمِرَ بِهِ طَيِّبًا بِهَا نَفْسُهُ أَحَدُ الْمُتَصَدِّقَيْنِ " .
It was narrated that Abu Musa said: "The Messenger of Allah said: 'The believers are like a building they support one another.' And he said: "The trustworthy storekeeper who gives that which he has been commanded to give, and is happy with what he is doing, is one of the two giving charity."'
