Is it required to perform Istibra' (period of waiting/abstinence) before marrying a woman immediately after freeing her?

Primary text

If a man wishes to marry a woman immediately after freeing her, he is not required to perform Istibra', regardless of whether he had intercourse with her or not. This is because Istibra' is mandated for the preservation of lineage (sperm), and lineage preservation is not a concern in this scenario.
