Abu al-Zubayr (may Allah have mercy on him) said that he heard Jabir (may Allah be pleased with him) saying: "When you have paid the zakah of your treasure (kanz), its evil has gone."
He narrated it as mawquf (a statement of the Companion), and this is more correct; it has also been narrated as marfu' (attributed to the Prophet) through another chain.
