What are the rulings concerning the inheritance of a deceased mother after a period of coma, especially regarding the father's payment of her deferred mahr, and how is its value calculated given currency depreciation, and is it deducted from his share of the inheritance, in addition to the ruling on paying zakat on her wealth for the year of her coma and the year following her death?

The deceased's property may not be divided except after their death. The deferred dowry becomes due upon death or separation, and the husband must pay it or deduct it from his share. If the currency value has depreciated, the dowry's value should be assessed based on its equivalent in gold or dollars at the time of death. This right transfers to the wife's heirs. Zakat on wealth for the deceased must be paid from their estate, and then the share of each heir is considered. Whoever's share reaches the nisab and a hawl has passed on it, must pay zakat on it.
