It is narrated from Tawoos, may Allah have mercy on him, that he states: The Messenger of Allah, peace and blessings be upon him, appointed Ubadah bin Samit, may Allah be pleased with him, as a collector of charity, and said: "O Abu al-Waleed! Fear Allah! Lest you come on the Day of Resurrection with a camel on your neck, and it is groaning, or a cow that is mooing, or a goat that is bleating." Ubadah bin Samit, may Allah be pleased with him, said: O Messenger of Allah! Is it really like that? The Messenger of Allah, peace and blessings be upon him, said: "Yes, by Him in Whose hand is my soul, except for the one upon whom Allah has mercy." Ubadah, may Allah be pleased with him, said: By Him Who has sent you with the truth, I will never again become an agent over even two things.
