حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي عَدِيٍّ عَنْ حُمَيْدٍ عَنْ رَجُلٍ مِنْ أَهْلِ مَكَّةَ يُقَالُ لَهُ يُوسُفُ قَالَ كُنْتُ أَنَا وَرَجُلٌ مِنْ قُرَيْشٍ نَلِي مَالَ أَيْتَامٍ قَالَ وَكَانَ رَجُلٌ قَدْ ذَهَبَ عَنِّي بِأَلْفِ دِرْهَمٍ قَالَ فَوَقَعَتْ لَهُ فِي يَدِي أَلْفُ دِرْهَمٍ قَالَ فَقُلْتُ لِلْقُرَشِيِّ إِنَّهُ قَدْ ذَهَبَ لِي بِأَلْفِ دِرْهَمٍ وَقَدْ أَصَبْتُ لَهُ أَلْفَ دِرْهَمٍ قَالَ فَقَالَ الْقُرَشِيُّ حَدَّثَنِي أَبِي أَنَّهُ سَمِعَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ أَدِّ الْأَمَانَةَ إِلَى مَنِ ائْتَمَنَكَ وَلَا تَخُنْ مَنْ خَانَكَ
A man from the people of Makkah named Yusuf says: I and a man from the Quraysh were guardians of some orphans’ wealth. It happened that a man (acting dishonestly) took one thousand dirhams from me, then one thousand dirhams of his came into my hands. I said to the Qurayshi: That person took one thousand dirhams of mine, now his one thousand dirhams have come to me, so should I keep this amount? He said: My father narrated that the Noble Prophet, peace and blessings be upon him, said: When someone makes you a trustee, then return his trust to him and do not betray him, even if he has betrayed you.
