The unity or duality of Vision option and Option of default description with an approach to the viewpoint of Imam Khomeini (RA)

There is a different opinion in the jurisprudence of Imamiyeh and Iranian law regarding the unity or duality of Vision option and Option of default description. Civil law has not taken a clear position in this regard, and mentioned these two Options in clause 5 of Article 396 together. It has been assumed that two Options have a single nature.Imam Khomeini, in Tahrir Al-vasilah, used the general title of Vision option for some cases that seems to be examples for Option of default description, but in the Al-Bai he explicitly state that the two options are distinct and separate from each other. In this paper, which is descriptive-analytic, by examining the given reasons, the viewpoint of Imam Khomeini means independency of two options has been strengthened and accepted on the basis of existing foundations.Accordingly, Option of default description exists when the goods are traded by description in the contract, but when the transaction is carried out with the description outside of contract and its collusion or on the former sighting, the Vision option will be available.
