The document discusses how the economic system of Islam aims to ensure the constant circulation of wealth by discouraging hoarding. It cites Quranic verses threatening those who hoard gold and silver with punishment. It states that zakat is a major deterrent against hoarding, as it would consume much of any hoarded wealth over several years, forcing the owner to invest or spend it. Other required and voluntary charitable practices, inheritance laws, and monetary penalties also help achieve the objective of keeping wealth in circulation.
