When a son predeceases his father, do his children inherit in their grandfather's estate?

Answer

When a child predeceases his parents, then for purposes of inheritance, he is non-existent. His children will not automatically inherit in their grandfather's estate. However, if the grandfather wishes, he may make a wasiyyat (bequest) for them. The total amount of the wasiyyat may not exceed one third the total value of his assets.
