...Although in the "Questions [&and] Answers" Baha'u'llah has specifically stated that non-Baha'is have no right to inherit from their Baha'i parents or relatives, yet this restriction applies only to such cases when a Baha'i dies without leaving a will and when, therefore, his property will have to be divided in accordance with the rules set forth in the Aqdas. Otherwise, a Baha'i is free to bequeath his property to any person, irrespective of religion, provided however he leaves a will, specifying his wishes. As you see therefore it is always possible for a Baha'i to provide for his non-Baha'i wife, children or relatives by leaving a will. And it is only fair that he should do so.
