It is narrated with the same chain that the Messenger of Allah (peace and blessings be upon him) said: "Whoever leaves behind a treasure, on the Day of Resurrection it will be made to appear for him as a bald serpent with two black spots (over its eyes). It will follow him and say: I am your treasure that you left behind you. It will keep following him until he puts his hand into its mouth, and it will chew it; then it will swallow the rest of his body in the same way."
