During the production process, various human and inhuman factors are involved, and without them there will be no way to formulate and work out the efforts made in this direction. But there is a significant issue in this regard, the amount of profit allocated to production operations to each of these factors. In the works of the Jurisprudents of the Shi'a religion, as well as in the language of the economy, there are different or contradictory views on the participation or non-participation of the means of production in the profit of the product, each of which are documented in considerations. Some people think that the share of the means of production is only rented, in contrast to others, in addition to rent, they also consider the participation of the means of production in the profit of the product. This article seeks to answer this question by relying on the opinions of the jurists, in particular the martyr Sadr (RA), who deals more with the jurisprudential aspect than others, and shows that it can be used for the means of production, in addition to renting The cost was considered as a share of the product's profit.
