It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: On the Day of Resurrection, the treasure of the one who hoarded wealth will become a bald snake. The owner will run away from it, and it will follow him, saying, "I am your treasure." By Allah, it will keep following him until he (the owner) puts his hand into its mouth and it chews it up, and then (swallows) the rest of his body as well.
