“A third group of people see the highest felicity in the abundance of property and the extension of ease. After all, property is an instrument to achieve the object of appetite. Through it, the human being attains the ability to achieve wishes. Hence, these people aspire to gather property; to increase estates, land, valuable horses, cattle, and farmland, and to hoard dinars in the earth. Hence, you will see one of them striving throughout life --- embarking on great dangers in the deserts, on journeys, and in the oceans to gather possessions with which he is niggardly toward himself, to say nothing of others. These are the ones meant by the words of The Prophet: "The slave of the dirham is miserable: the slave of the dinar is miserable." What darkness is greater than that which deceives the human being? Gold and silver are two stones that are not desired in themselves. When wishes are not achieved through them and they are not spent, then they are just like pebbles, and pebbles are just like them.”
