Sayyiduna Ibn Umar (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, the person who does not pay the zakat of his wealth, (his wealth) will take the form of a bald snake for him, which will have two black spots over its eyes. It will cling to him or become a collar around his neck and will say, 'I am your treasure.'" This narration is from Ahmad bin Sinan, and Zafarani says that Abdullah bin Dinar told me that Sayyiduna Ibn Umar (may Allah be pleased with them both) said, "So it will become a collar around his neck or it will cling to him."
