What should Mrs. (B) do with the money Mrs. (A) entrusted to her, with instructions not to give it to her daughter, knowing that this daughter has become the sole heir of Mrs. (A) after her death? Should she execute the will or give the money to the inheriting daughter?

The contextual clues must be considered. If Madam "A" advised Madam "B" not to give her daughter any money at all, then if the money is one-third or less, it is considered charity. If it exceeds one-third, the excess amount is returned to the estate and divided. However, if the intention was to prohibit giving money only during lifetime, then the money is returned to the estate to be divided. If neither of these two interpretations is favored, then the prohibition applies only during lifetime.
