Is a bequest made for the fetus a pregnant woman is carrying valid?

Primary text

The bequest made for what a pregnant woman is carrying is invalid. This ruling is based on the principle that a bequest (*wasiyya*) is a transfer of ownership, which cannot be made to something non-existent. This is analogous to inheritance (*mīrāth*); only existing heirs inherit from the deceased, not a fetus unless it is already in existence. The validity of the inheritance of blood money (*diyyah*) which is determined after death, despite being established through bequest, serves as an exception because it is an established right that can be quantified after the death of the cause.
