What is the effect of Li'an (Mutual Imprecation) on the Iddah of the wife?

Primary text

In the case negated by Li'an, the child is negated from the husband, but the ruling concerning the wife's Iddah is upheld. The negation of the child's lineage from the husband also negates his status as the father concerning the wife, which necessitates imposing the punishment upon the accuser (Qadhif) and the accuser of the child. However, the termination of her Iddah remains a ruling pertaining to her exclusively and thus remains established.
