Sahih al-Bukhari · No. 2319Chapter 40
" الْخَازِنُ الأَمِينُ الَّذِي يُنْفِقُ ـ وَرُبَّمَا قَالَ الَّذِي يُعْطِي ـ مَا أُمِرَ بِهِ كَامِلاً مُوَفَّرًا، طَيِّبٌ نَفْسُهُ، إِلَى الَّذِي أُمِرَ بِهِ، أَحَدُ الْمُتَصَدِّقَيْنِ "
The Prophet (ﷺ) said, "An honest treasurer who gives what he is ordered to give fully, perfectly and willingly to the person to whom he is ordered to give, is regarded as one of the two charitable persons."
