It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "Whoever does not pay the zakat of his wealth, on the Day of Resurrection his wealth will come in the form of a bald snake with two black spots over its eyes. That snake will be made into a collar and hung around his neck, and it will say to him, 'I am your treasure, I am your treasure.'"
