Is it more appropriate to carry out the deceased's will to distribute the amount of 24,0 (4,0 to the cancer hospital, 8,0 to the son, and 4,0 to each of the three daughters), or to give out only the amount designated for the cancer hospital and distribute the rest according to Sharia, especially since the husband is still alive and not included in the will, and the wife was the authorized agent for her mother's money and had the right to dispose of it during her lifetime?

The woman's bequest of the aforementioned amount to the cancer hospital is a valid and enforceable will, as it does not exceed one-third of the estate. However, her bequest regarding the specific division of the remaining estate is not enforceable, as it contradicts Islamic Sharia by disinheriting the husband and increasing the share of the sons and daughters. This is considered an act of harm in a will and is a grave sin. Therefore, what remains after the execution of the will must be divided among all heirs according to the Islamic legal distribution of inheritance. The daughter who was an agent for her mother has no right to dispose of the estate after her mother's death or to restrict the heirs.
