Concerning the subject of treasury and the subject of the rights of the people Imam had much precision; his life was as such that it did not differ from the life of common people.
Concerning the buying of the necessity goods of his home he recommended much that things should be bought that would be to the usual degree of the life of the scholastics.
Imam was saying that you should buy a thing that all others have the power to buy it; he always emphasized that you should shorten the purchase and you should buy what are necessary; do not be wasteful and do not indulge in extravagance.
