Iddah (waiting period)
2526. If a woman is free and is not pregnant and her
husband dies, she should observe Iddah (the waiting period) for four months
and ten days, that is, she should not marry during that period even if she has
entered into menopause or her husband had contracted temporary marriage with
her, or he may not have had sexual intercourse with her.
If, however, she is pregnant, she should observe the waiting period till the birth of the child. But if the child is born before the end of four months and ten days from the death of her husband, she should wait till the expiry of that period. This period is called the waiting period after death (Iddatul Wafat).
2527. It is haraam for a woman who is observing the Iddah of death to wear brightly coloured dress, or to use surma and to do any such act which is considered to be an adornment.
2528. If a woman becomes certain that her husband has
died, and marries another man after the completion of Iddah of death, and later
on learns that her husband had died later, she should separate herself from
her second husband.
And as a precaution, if she is pregnant, she should observe Iddah of divorce for the second husband till she gives birth to a child, and should thereafter observe Iddah of death for the first husband. But if she is not pregnant, she should first observe Iddah of death for her first husband and thereafter she should observe Iddah of divorce for the second husband.
2529. The Iddah of death begins, in the situation when the husband has disappeared or is absent, when the wife learns of his death, and not from the time when he actually died. But this rule does not apply to a wife who has not attained the age of Bulugh, or if she is insane.
2530. If a woman says that her Iddah is over, her word can be accepted unless she is known to be unreliable, in which case, her word will not be accepted. For example, if she claims to have seen blood three times in the month, her claim will not be trusted, except when her women relatives confirm that it is her habit.
