In the event of the husband's failure, either to return at the end of the specified period of time or to notify his wife of a delay, the wife must wait nine months, after which she is free to remarry, though it is preferable for her to wait longer (see note 147 for the Bahá'í calendar).
Bahá'u'lláh states that, in such circumstances, should news reach the wife of "her husband's death or murder", she must also wait nine months, prior to remarrying (Q and A 27). 'Abdu'l-Bahá, in a Tablet, has further clarified that the nine months' waiting period following news of the husband's death applies only if the husband had been away at the time of his death, and not if he dies while at home.
