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.
