The Statement of Allah: ...And those who hoard up gold and silver (AI-Kanz—the money, the Zakãt of which has not been paid) and spend it not in the Way of Allah—announce to them a painful torment. (V.9:34)

Allah's Messenger (ﷺ) 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."

I passed by (visited ) Abu Dhar at Ar-Rabadha and said to him, "What has brought you to this land?" He said, "We were at Sham and I recited the Verse: "They who hoard up gold and silver and spend them not in the way of Allah; announce to them a painful torment, " (9.34) where upon Muawiya said, 'This Verse is not for us, but for the people of the Scripture.' Then I said, 'But it is both for us (Muslim) and for them.' "
