Abu Dharr (May Allah be pleased with him) reported:
I said to Messenger of Allah ﷺ: "Why do you not appoint me to an (official) position?" He ﷺ patted me on the shoulder with his hand and said, "O Abu Dharr, you are a weak man and it is a trust and it will be a cause of disgrace and remorse on the Day of Resurrection except for the one who takes it up with a full sense of responsibility and fulfills what is entrusted to him (discharges its obligations efficiently)."

[Muslim].

وعنه قال: قلت يا رسول الله ألا تستعملني؟ فضرب بيده على منكبي ثم قال: “يا أبا ذر إنك ضعيف، وإنها أمانة، وإنها يوم القيامة خزي وندامة، إلا من أخذها بحقها، وأدى الذى عليه فيها” ((رواه مسلم)).
