Fatwas on Hoarding and Extravagance

Q1457: What are the things that are ḥarām to hoard? And do you authorize the imposition of financial penalties on hoarders?
A: According to transmitted traditions and the most famous view, things that are forbidden to be hoarded are confined to the four crops (wheat, barley, dates, and raisins) and animal / vegetable fat which are commonly used by different sections of the society. However, if the public interest necessitates, the Islamic state has the jurisdiction to ban the hoarding of all that the people need. There is no objection to imposing financial penalties on hoarders if the judge thinks fit.
