And the evidence that the hoarded treasure (al-kanz) is the wealth from which zakat is not paid, not the buried wealth from which zakat is paid.

Sayyiduna Abdullah (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him) that he said: "Whoever does not pay the zakat of his wealth, then on the Day of Resurrection a snake will be made for him which will become a collar around his neck on the Day of Resurrection." Then the Noble Prophet (peace and blessings be upon him) recited this verse of the Qur'an in confirmation of this: «‏‏‏‏سَيُطَوَّقُونَ مَا بَخِلُوا بِهِ يَوْمَ الْقِيَامَةِ» ‏‏‏‏ [ سورة آل عمران: 180 ] "The wealth in which they were miserly, it will be made into a collar for them on the Day of Resurrection."

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."
