How is the inheritance divided for a man who died leaving behind four sons and three daughters from his first divorced wife, a second wife and a daughter from her, a mother who is still alive, and two half-sisters from his mother's side, with two houses, one of which was sold to the second wife and the other bequeathed to the heirs, and does the wife inherit from the second house if she requests it, and do the sons have the right to challenge the sale of the house to the second wife given the father's illness at the time of the sale, and do the grandchildren inherit from their grandmother after her death or does the inheritance go to her daughters?

A wife who is revocably divorced inherits if her husband dies while she is still in her waiting period ('iddah).

The inheritance is distributed as follows: The wife or wives receive one-eighth, the mother receives one-sixth, and the remainder goes to the sons and daughters by way of ta'sib, with the male receiving the share of two females. The two sisters from the mother's side do not inherit due to the presence of sons and daughters.

A will made to an heir is not enforceable unless all adult, sane heirs approve it.

A sale made by a terminally ill person is valid, but if he favors one of the heirs, then the gift to that heir depends on the approval of the remaining heirs. The determination of whether paralysis is a terminal illness should be referred to trustworthy doctors.

The maintenance of a poor father is obligatory upon his children and is distributed according to their financial capability. If the father is wealthy, then the expenses for maintenance and treatment are considered a debt upon him unless the children voluntarily contribute them.

This matter must be referred to the Sharia court to examine its details, as inheritance issues are critical and complex.
