Should the mother give away in charity all the money left with her as a trust by the lady, or only a third of it, with the remainder given to her children, knowing that the lady stipulated that all the money be given away in charity and none of it given to her children?

Gifts contingent upon death are bequests subject to the rulings of a will. Thus, they are not valid for an heir, and their value must not exceed one-third of the estate. If the aforementioned money constitutes all that the deceased owned, then it is not permissible to donate all of it as charity; rather, only one-third of it may be donated, unless the adult and mature heirs approve of it. However, if she had other assets and the deposited amount was one-third or less, then the bequest is valid.
