Ata' (may Allah have mercy on him) related that Sayyiduna Imran bin Husayn (may Allah be pleased with him) was appointed as collector over the sadaqah (zakah). He went and then returned, and the people said to him: Where is the wealth? He said: "Was it for wealth that you sent me? We took it just as we used to take it in the time of the Messenger of Allah (peace and blessings be upon him), and we distributed it just as we used to distribute it."
