Is it permissible to allocate a sum of money inherited by the wife from her deceased husband to their young, unmarried, and unemployed daughter, for her education and marriage expenses, and not distribute it among the rest of the heirs?

The estate left by the husband is to be divided among all his heirs after settling his debts and executing his will within one-third of his wealth. It is not permissible to allocate a specific amount to one of the daughters unless all the heirs agree and waive their right; otherwise, the wealth must be divided among the heirs, each according to their rightful share.
