Was the father's giving of half his deceased daughter's money and gold to her husband, in his capacity as guardian of their six-year-old daughter, correct, and does she have a share in the amount given by the charity?

If a daughter dies with her husband and children, and there is doubt about who died first, they do not inherit from each other. What each of them left behind is distributed among their living heirs. Half of what the daughter left is given to her daughter if she is the only child. The other half goes to the father if the mother is not present. If the mother is present, she receives one-sixth, and the remainder goes to the father as a prescribed share and by agnatic kinship. As for what the charity organization provides, it is distributed according to what the organization specifies. It must be emphasized that inheritance issues are serious and require being brought before the Sharia courts for investigation, to determine the heirs, and to settle wills and debts, as these take precedence over the rights of the heirs.
