What is the ruling if an animal designated for sacrifice (after initial purchase) is found to have a defect?

Primary text

If the animal was designated for sacrifice and then found to be defective, the person is given the choice to return it or take the *arsh*. If the *arsh* is taken, its handling follows the ruling established for an excess value beyond the animal's worth. However, a strong opinion states the *arsh* belongs to the buyer because the designation (*ijab*) occurred when the defect was absent, hence the designation did not affect the right to compensation.
