Narrated from Sayyiduna Sa’d bin ‘Ubadah (may Allah be pleased with him), he says: The Noble Prophet (peace and blessings be upon him) said to me: Get up and collect zakat from such-and-such tribe and be careful, lest you come on the Day of Resurrection carrying a camel on your shoulder that is groaning. Upon hearing this, Sayyiduna Sa’d (may Allah be pleased with him) said: O Messenger of Allah! Remove this responsibility from me. So the Prophet (peace and blessings be upon him) relieved him of this responsibility.
