Study of Dept to Dept Sale in Imamieh Jurisprudence

Although nullity of debt to debt sale is familiar amongst Islamic supreme jurists, there is no valid reason for invalidity of sale that either both of merchandise and price or one of them will become debt after forming contract. According to permission evidences of contract and principle of transactions validity, the mentioned sales are valid. Thus, based on this saying: “shouldn’t be sold debt to debt “,and considering making up defect of document by well-known action, nullity will be dedicated to unanimity, which both of merchandise and price are debts after forming contract. According to this view, most of sales that have been contracted nowadays in which both of merchandise and price will become debts after forming contract will exclude the title of debt to debt sale, specially in seriously common contracts in stock market and international trades and particularly in oil future contracts, and so the fundamental obstacle in commercial relationship, causing fault and hardship, will be eradicated.
