Hazrat Abu Wa'il narrates that I heard from Hazrat Abdullah, who, in the explanation of Allah Almighty's command { سَیُطَوَّقُوْنَ مَا بَخِلُوْا بِہٖ یَوْمَ الْقِیٰمَۃِ }, said that on the Day of Resurrection, a serpent will be made into a collar and placed around their neck. It will have two black spots on its mouth, it will hiss and say, "I am that very wealth of yours in which you used to be miserly."
