What is the ruling on wives' inheritance in a case where one of them is divorced and the husband marries another during her 'iddah (waiting period), then the husband dies before the 'iddah of the divorced wife ends, and is the divorced wife required to resume her 'iddah?

If the divorce is revocable, the divorced woman inherits. However, the fifth wife, whom he married before the divorced woman's waiting period (iddah) ended, does not inherit because her marriage contract (nikah) is invalid.

If the divorce is irrevocable (the third divorce), the divorced woman does not inherit. However, the fifth wife does inherit due to a significant difference of opinion among scholars regarding the validity of this marriage, and the opinion allowing it is strong.

If the husband dies during the waiting period of a revocable divorce, the divorced woman transitions to the waiting period for death (four months and ten days). However, if the divorce was irrevocable, the divorced woman completes her divorce waiting period and does not observe the waiting period for death.
