Do real estate and stocks fall within the bequest of "one-third of my wealth," or is it limited to cash only?

If the testator dies, the reference point for determining what their will includes is the custom and language of their country. So, if "wealth" (مال) in the custom of their country includes cash and other assets, then the will must be executed for all that they left behind. However, if the custom restricts "wealth" to only cash, then the will does not extend to other assets except with the consent of the heirs. This is because the testator's wording is interpreted according to their usual manner of speech and the language they use, as the intent of words is their indication of what the speakers mean by them.
