Do the deceased wife's husband and children inherit from her father who passes away later, and does the ruling differ if she had no one but a husband?

The daughter's husband is not among the heirs, unless he inherits from another relation, such as being his father-in-law's nephew. The daughter's son and daughter do not inherit from their maternal grandfather; rather, they are considered relatives by blood (dhawi al-arham). If a woman dies and leaves behind a husband, children, and a father, then the father receives one-sixth, the husband one-fourth, and the remaining portion goes to the children by way of ta'sib (residuary inheritance), with the male receiving the share of two females. It must be noted that inheritance matters are complex and require presentation to religious courts for investigation to ensure there are no other heirs, wills, debts, or rights that take precedence over the heirs' rights.
