What is the ruling if one party in the prohibited intercourse (following triple divorce) is knowledgeable and the other is ignorant?

Primary text

If the husband is the knowledgeable party and she is ignorant, the *had* is upon him, the *mahr* is due to her, but lineage is not established, as he is a punishable adulterer. If the wife is the knowledgeable party and he is ignorant, the *had* is upon her alone, no *mahr* is due to her, and lineage is established to the husband because his act was intercourse based on a misunderstanding (*shubhat wat'*).
