Is it permissible to execute the mother's will to buy a car for her daughter from the price of her personal gold jewelry after her death? And is her jewelry to be divided as she willed, or is it subject to the laws of inheritance? And is it true that the deceased does not benefit from any type of charity given on their behalf?

It is permissible to execute the mother's will regarding the car to one of the heirs if the remaining heirs agree willingly, based on the hadith: "There is no will for an heir unless the heirs wish it." It is also permissible to divide the gold among the daughters by mutual consent if the heirs agree to it. Furthermore, the deceased's benefit from their children's charity given on their behalf is established by hadith, even if the charity was not from their original wealth after their death.
