AoA,
Volume 9, Number 89:
Narrated Abu Huraira:
Allah’s Apostle (salla llahu alayhi wa sallam) 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(sallallahu alayhi wa sallam) added, “By Allah, that snake will keep on following him until he stretches out his hand and let the snake
swallow it.”
Allah’s Apostle(salla llahualayhi wa sallam) added, “If the owner of camels does not pay their Zakat, then, on the Day of Resurrection those camels will
come to him and will strike his face with their hooves.” Some people
said: Concerning a man who has camels, and is afraid that Zakat will
be due so he sells those camels for similar camels or for sheep or
cows or money one day before Zakat becomes due in order to avoid
payment of their Zakat cunningly! “He has not to pay anything.” The
same scholar said, “If one pays Zakat of his camels one day or one
year prior to the end of the year (by the end of which Zakat becomes
due), his Zakat will be valid.”
(Sahih Bukhari)
“I put my trust in Allah, my Lord and your Lord! There is not a moving creature, but He has a grasp of its forelock. Verily, my Lord is on the straight path. (The truth)”
