What is the ruling on the inheritance of a man who died and left behind a wife, five daughters, and four sons, then one of the daughters died leaving behind a husband and a mother?

If an heir dies before the distribution of the inheritance, their share does not lapse; rather, it is preserved for them and given to their heirs. So, if a man dies leaving behind a wife, five daughters, and four sons, the wife receives one-eighth due to the existence of a inheriting offspring (for if you have a child, they get an eighth of what you leave), and the remainder goes to the children, with the male receiving the equivalent of the share of two females (Allah instructs you concerning your children: for the male, what is equal to the share of two females).

Then, the share of the deceased daughter from her father's estate, along with her other possessions, is distributed among her living heirs. If the daughter leaves behind a husband, a mother, and siblings, the husband receives one-half (and for you is half of what your wives leave if they have no child), and the mother receives one-sixth due to the presence of a group of siblings (but if he has brothers, his mother gets a sixth), and the remainder goes to the siblings, with the male receiving the equivalent of the share of two females.
