Is a verbal will documented by witnesses, in addition to a written will from the workplace—which the deceased believed would guarantee her nephews (whom she was supporting) all her possessions—considered valid and enforceable, especially since her husband did not provide for her and procrastinated divorcing her?

The husband's bad behavior does not prevent him from inheriting as long as the marriage contract is valid and there is no impediment. A will for more than one-third of the estate, whether to a non-heir or to an heir, is invalid and is not enforceable except with the consent of the heirs. If the husband does not agree to the will exceeding one-third, the beneficiaries receive one-third of the estate, and the husband takes half of what remains from the two-thirds. The remaining money is taken by the beneficiaries if the rest of the heirs agree. In case of disagreement, the matter must be referred to the Sharia (definition) court or Sharia arbitration.
