The Messenger of Allah ﷺ said, "The trustworthy treasurer who delivers what he has been ordered to give, in full and complete measure, with a willing heart, handing it over to the one for whom it was intended, is one of the two givers of charity."
حدثنا عثمان بن أبي شيبة ومحمد بن العلاء المعنى واحد قالا حدثنا أبو أسامة عن بريد بن عبد الله بن أبي بردة عن أبي بردة
قال رسول الله ﷺ إن الخازن الأمين الذي يعطي ما أمر به كاملا موفرا طيبة به نفسه حتى يدفعه إلى الذي أمر له به أحد المتصدقين
