What did the Prophet Muhammad (peace be upon him) say about the Kanz (money) of a person that has not been paid as Zakat on the Day of Resurrection?
 Narrated Abu Huraira:                     Allah's Apostle said, "The Kanz (money, the Zakat of which is not paid) of anyone of you will appear in the form of bald-headed poisonous male snake on the Day of Resurrection."
