Does the failure to explicitly name the wife in the marriage contract affect its validity, especially since her sister is not marrying in their country and those present know who the intended bride is?

Among the most important conditions for the validity of a marriage contract is the designation of the spouses. This designation is achieved by name, اشاره, description, or any characteristic that distinguishes the intended contracting party. Thus, if a guardian has more than one daughter and says, "I marry you to my daughter," the contract is not valid unless he specifies her by name or description. However, if the contracting parties and the witnesses know the wife intended by the contract, then the designation is achieved and the contract is valid. The guardian's not mentioning the wife's name does not cause harm, and scholars have explicitly stated the validity of the contract in such a case. If the two parties agreed upon one (daughter) before the contract and intended her at the time of the contract, and the witnesses were aware of her, then the contract is valid.
