This question turns on one issue in our madhhab register: Does a divorced spouse inherit? — does a divorced spouse inherit, and does the answer change during the ‘idda?

The two things that are not in dispute. First, the revocable divorce. While the ‘idda of a raj’i divorce is running, husband and wife still inherit from each other, and it makes no difference whether the divorce was pronounced in health or in illness. Ibn Qudama states it and closes the door on it: “with no disagreement that we know of”, reported from Abu Bakr, ‘Umar, ‘Uthman, ‘Ali and Ibn Mas’ud — the reason being that a revocably divorced woman is still a wife, whom he may take back without her consent and without a new contract, guardian, witnesses or dower. The Kuwaiti Mawsu’a reports the same as the position of the jurists, and makes it the second condition of spousal inheritance: the marriage must subsist at death in fact or in law, and the ‘idda of a revocable divorce is the case of “in law”. Second, the irrevocable divorce given in health. Where a man divorces his wife while well and the ‘idda then expires, Ibn Qudama says the two “do not inherit from each other, by consensus”, and the encyclopaedia adds that this holds whether or not she consented. Everything above turns on the third case only: the irrevocable divorce pronounced in a final illness.
