Narrated Abu Huraira: Allah's Messenger (ﷺ) said, "On the Day of Resurrection the Kanz (Treasure or wealth of which, Zakat has not been paid) of anyone of you will appear in the shape of a huge bald headed poisonous male snake and its owner will run away from it, but it will follow him and say, 'I am your Kanz.'" The Prophet (ﷺ) added, "By Allah, that snake will keep on following him until he stretches out his hand and let the snake swallow it."
