Does the buyer have the option to annul the contract if the item matches the stipulated description?
Chapter on the Option of the Two Parties in Sale
Al-Mughni
Book of Sales
Primary text
If the buyer finds the object to conform exactly to the stipulated description, he does not possess the option to rescind the sale. This is based on the principle that the object of the contract was delivered with its specifications, similar to the delivered item in a Salam contract, which does not grant an option. Moreover, since it is a described sale, the contracting parties should not have an option in all situations, similar to Salam.

Al-Thawri, Abu Hanifa, and his companions assert that the buyer has the option in all cases, labeling it the 'option of seeing' (Khiyar al-Ru'yah), arguing that seeing is integral to the contract's completion, resembling an undescribed sale.
