Article 188 of the Civil Code, in the definition of optional contract, stipulates that the optional contract is one that can be terminated by the parties or one of them or by a third party. Based on this, it can be said that the sale of cucumbers, as stated in Article 399 of the Civil Code, is a sale that can be terminated by the parties or one of the parties or one of them or a third party. In the works of jurists, sometimes the sale of cucumbers is considered synonymous with the sale of a condition, while the concept of sale of a cucumber is different from the sale of a condition, and it may be possible to consider the sale of a condition as one of the types of sale of a cucumber. In all types of sales, including optional sales, according to the law, as soon as the contract is concluded, the seller is the owner of the price and the customer is the owner of the sale, and he has the right to interfere and occupy the property, even to transfer it. It is the future and as a rule, it is not possible to return the merchandise that is not with the customer, and in case of cancellation, the customer must return the same or the price of the merchandise.
