A woman asked Imam Ibrahim al-Nakha'i (may Allah have mercy on him), "I have continuous bleeding." He said: "Sprinkle water, it will stop the blood for you."

It is narrated from Imam Hasan, may Allah have mercy on him, regarding the divorced woman whose menstruation is not known (i.e., whether it comes or has stopped), he said: She will wait for a full year; if menstruation occurs, then fine, otherwise after one year she will observe the waiting period ('iddah) for three months. Then if menstruation occurs, then fine; if it does not occur, then her 'iddah is complete.

Imam Malik, may Allah have mercy on him, was asked about the divorce of a woman suffering from istihada (non-menstrual bleeding), so he narrated from Ibn Shihab (al-Zuhri) from Sa'id ibn al-Musayyib, may Allah have mercy on them both, that her waiting period ('iddah) is one year. Imam al-Darimi, may Allah have mercy on him, said: This is the statement of Imam Malik, may Allah have mercy on him.

Amr bin Dinar said: Jabir bin Zaid was asked about the divorce of such a young girl, who, without reaching old age, has stopped menstruating (what will be her waiting period?). He replied: She will observe a waiting period equal to that of menstruating women. Imam Tawus, may Allah have mercy on him, explained: She will observe a waiting period of three months.

It is narrated from Mu’ammar that Imam Zuhri, may Allah have mercy on him, said: When a man divorces his wife and after one or two menstruations she stops (menstruating), and this cessation is due to old age, then she will complete three months of ‘iddah. And if she is of young age and falls into doubt, then after the doubt arises, she will observe ‘iddah for one year.

It is narrated from Qatadah: Ikrimah (the freed slave of Sayyiduna Ibn Abbas, may Allah be pleased with them both) said: The woman experiencing istihada (irregular bleeding) and the woman whose menstruation is not regular—sometimes she menstruates once a month, sometimes twice—their waiting period (‘iddah) will be three months (i.e., the waiting period after divorce).

It is narrated from Hisham, Hammad said: She will observe the waiting period of three quro’ (i.e., three menstrual cycles).

Saeed bin Al-Musayyib (may Allah have mercy on him) said: The waiting period (‘iddah) of a woman with continuous bleeding (mustahadah) is one year.

Imam Hasan, may Allah have mercy on him, said: A woman experiencing istihada will observe the waiting period according to the days of her menstruation; that is, if she is divorced, her waiting period is three periods (qur’).

Imam Zuhri, may Allah have mercy on him, said: She will observe the waiting period (‘iddah) according to“qur’”(i.e., by counting menstruation or purity). Imam Darimi, may Allah have mercy on him, said: The people of Hijaz interpret“qur’”as the state of purity, and the people of Iraq interpret it as the state (and duration) of menstruation. Imam Darimi, may Allah have mercy on him, said: And in my view, it is menstruation.
