Legal Status of Unreasonable (Safahi) Transactions in Imami Fiqh and Iranian Law

Unreasonable (Safahi) transactions are in a position to be done bySafih (fool dealer) but here the dealer is not really a Safih. Rahter he has perfection of concious, reason and will and is free from any coercion insigning the contract. These deals have instances and rules the understanding of which requires knowledge of their nature and the method to recognize them. Unreasonable transactions (Safahi) are not related to detrimental contracts and in all contracts and even conditionals and unilateral transactions (Iqaat) can be seen. The best criterion to distinguish these transactions is investigating the motive of the transaction. The lack of rational motive behind a deal makes the transaction an unreasonable transaction (Safahi). For the recognition of rational motive one must refer to the customary practice. The legal status of these transactions is disputed among Imami scholars and jurists. Some believe these transactions are valid and some believe in their voidness and both have evidence being criticized by the other party. These transactions are valid, here we will argue considering Iranian legal system, because of having necessary elements of contracts.
