What is the ruling if two heirs co-own wealth subject to mixed ownership (Khiltah), and one dies mid-Hawl, with the surviving partner inheriting the deceased's share?

Primary text

This situation is analogous to the previous case concerning mixing partners. Following Abu Bakr's ruling, the survivor owes nothing until the Hawl is completed on the totality of the wealth from the moment he owned both shares, unless one share alone meets the Nisab threshold.
