menstruation. Moreover, she is one of those with menstrual cycles (dhawat al-quru'), so her 'idda is a year, like the one whose menstruation has ceased. According to the first narration, it should be said: Whenever we judge that her menstruation is seven days per month, and two months by the lunar calendar have passed, plus seven days of the third month, her 'idda has terminated. And if we say: The 'quru' are periods of purity (at-tuhur), and he divorced her at the end of a month, then two months passed and the third month began, her 'idda has terminated. This is the school of al-Shafi'i.

1349 - Issue: He said: (And if he divorced her while she was among those who do not menstruate, and her 'idda had not yet terminated by the months until she menstruated, she begins a new 'idda of three menstrual cycles if she is a free woman, and two menstrual cycles if she is a slave woman).

The sum of it is that the young girl who has not yet menstruated, or the adult woman who has not menstruated, if she observed the 'idda by the months, then menstruated before her 'idda terminated, even if by an hour, it becomes binding upon her to restart the 'idda. This is the opinion of the generality of the scholars of the cities, among them Sa'id ibn al-Musayyib, al-Hasan, Mujahid, Qatadah, al-Sha'bi, al-Nakha'i, al-Zuhri, al-Thawri, Malik, al-Shafi'i, Ishaq, Abu 'Ubayd, the people of opinion (Ashab al-Ra'y), the people of Medina, and the people of Basra. This is because the months are a substitute for the menstrual cycles, and when the original (that which is replaced) is found, the ruling of the substitute is nullified, just like tayammum in the presence of water. It is binding upon her to observe an 'idda of three menstrual cycles if we say: The 'quru' are menstrual cycles. And if we say: The 'quru' are periods of purity, then does she count the elapsed portion of the purity before the menstruation as a 'qur'? There are two views: One of them is that she counts it; because it is a purity from which she transitioned to a menstruation, so it is similar to the purity between two menstruations. The second is that she does not count it; and this is the evident opinion in the speech of al-Shafi'i; because the 'qur' is the purity between two menstruations, and this was not preceded by a menstruation, so it is not a 'qur'. However, if her 'idda had terminated by the months, then she menstruated after it, even if by a moment, it is not binding upon her to restart the 'idda; because this is a meaning that occurred after the termination of the 'idda, like one who menstruated long after the termination of the 'idda. It is not possible to prohibit this principle, because if its prohibition were correct, one who does not menstruate would never be able to observe an 'idda by the months in any condition.
