Is it permissible for a man to wash his deceased divorced wife if she died while still in her waiting period (iddah)?

One spouse is permitted to wash the other. If a wife dies during her waiting period (iddah) after a revocable divorce, her husband is permitted to wash her, and vice versa, because she is still considered his wife. However, if the divorce was irrevocable (for compensation or a triple divorce), neither of them is permitted to wash the other due to the termination of the marital relationship.
