In this paper, after explaining a problem of the business ethics and referring to its general history, it is claimed that retailers do not have to sell goods according to the price of the time of buying, but they have the right to sell their goods at the price market. After the definition, of the property and the economic value, three principles have been used to proof of the claim: 1. necessity of preservation of property, 2. la zarar (لاضرر), and 3. Golden Rule. Finally, in explaining the opposition's arguments like self-sacrifice in Islamic ethics, have been concluded that it is good to sell according to a former price, but it does not obligatory. Two other arguments of the opposition are the principles of asceticism (zohd) and justice. The method of study except rational reasoning is use of the Islamic traditions. We argue from Islamic jurisprudence theories some times.
