She becomes free when the period of her marriage expires or when the mam forgoes the perid of her marriage by saying, I hereby exempt you from the remaining time of marriage, and it is not necessary to have a witness nor that the woman should be pure from her Haydh. Iddah of Divorce (The Waiting Period after Divorce) A wife who is under nine and who is in her menopause will not be required to observe any waiting period.
It means that, even if the husband has had sexual intercourse with her, she can remarry immediately after being divorced. If a wife who has complated nine years of her age and is not in menopause, is divorced by her husband after sexual intercourse, it is necessary for her to observe the waiting period of divorce.
the waiting period of a free woman is that after her husband divorces her during her purity period she should wait till she sees H “ayd “twice and be comes pure if the time between two menses is less than three months. Thereafter, as soon as she sees Hayd for the third will be over and she can marry again.
If, however, a husband divorces his wife before having sexual intercourse with her, there is no waiting period for her and she can marry another man immediately after being divorced, except if some semen of her husband in any way has entered into her vagina, in which case she should observe Iddah.
If a woman does not see Haydh or menstruates but the period between two menses is three months or more who normally see Hayd, and her husband divorces her after sexual intercourse, she should observe Iddah for three lunar months after divorce. If a woman whose Iddah is of three months, is divorced on the first of a lunar month, she should observe Iddah for three lunar months, that is, for three months from the time the new moon is sighted.
And if she is divorced during the month, she should observe Iddah for the remaining days in the month added to two months thereafter, and again for the balance from the fourth month so as to complete three months.
For example, if she is divorced on the 20th of the month at the time of sunset and that month is of 30 days, she should observe Iddah till the sunset of 20th of the fourth month, and if that month is of 29 days she should, as an obligatory precaution, observe Iddah for nine days of that month and the two months following it, and for twenty one days of the fourth month so that the total number of the days of the first month and the fourth month comes to thirty.
