What is the ruling if the husband accepts the gift or bequest of the mother before the son accepts?

Primary text

If the husband accepts first, the entire unborn child is emancipated through him: his share by virtue of ownership, and the remainder by extension (*sarāyā*). He owes compensation for the child's value. Subsequently, when the son accepts, the entire mother is emancipated by the son. They then reconcile their shares (*yataqāṣṣān*), and each must return the excess value to the other party.
