If a girl...
If a girl, who has completed nine lunar years of her age and is not a menopause, is divorced by her husband after sexual intercourse, it is necessary for her to observe the waiting period or divorce. The waiting period of a woman is that when her husband divorces her while she is free of menses she should wait till she has menses twice and then is purified. Thereafter, as soon as she has menses for the third time her waiting period comes to an end and she can marry again.
In case, 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 by her husband. **2521.**If a woman, who does not have menstrual discharge, is of the age of women who have menstrual discharge, and her husband divorces her after sexual intercourse, she should observe iddah for three months after divorce. 2522.
If a woman whose iddah is of three months is divorced on the first of a month she should observe iddah for three lunar months (i.e. for three months from the time the moon is sighted). And if she is divorced during the month she should observe iddah for two months thereafter and for as many days of the fourth month as are short of the first month so that the total may come to three months.
For example, if she is divorce on the 20th of the month at the time of sunset and that month is of 29 days she should observe iddah for nine days of that month and the two months following it and for twenty days of the fourth month. And the recommended precaution is that in the fourth month she should observe iddah for twenty-one days so that the total number of the days of the first month and the fourth month comes to thirty. 2523.
If a pregnant woman is divorced her iddah lasts till the birth or abortion of the child. Hence, if, for example, she gives birth to a child one hour after being divorced, her iddah comes to an end. 2524.
If a woman who has completed nine years of age and is not menopause contracts a fixed time marriage for example, if she marries a man for a period of one month or one year and the period of her marriage comes to an end or her husband excuses her the remaining period of marriage she should observe Iddah.
Hence if she has menstrual discharge she should observe Iddah for two periods of menses and should not many a man during that period, and if she does not have menstrual discharge she should refrain from marrying a man for forty-five days.
