Is it permissible to execute the deceased woman's will to distribute four golden bangles to her four daughters, given the existence of other male and female heirs, and what is the share of each heir?

If a deceased woman leaves behind only one son and four daughters, her entire inheritance is distributed among them by way of ta'sib (residuary heirship), with the male receiving the share of two females, in accordance with Allah's saying: {Allah instructs you concerning your children: for the male, what is equal to the share of two females}.

The paternal cousin, the half-sister from the father's side, and the full- or half-siblings from the mother's side do not inherit due to the presence of the son.

The inheritance is divided into six shares: two shares for the son, and one share for each daughter.

As for the deceased's will to bequeath a portion of her estate to her daughters, it holds no validity and is not binding, because it is a bequest to an heir (wasiyya li-warith), and it is not enforceable unless approved by the adult, sane heirs.
