A man who divorces his wife while she has irregular bleeding (istihadah): by what does she count her waiting period?

Al-Hasan (may Allah have mercy on him) said: A woman with irregular bleeding (mustahadah) observes her waiting period ('iddah) by aqra' (periods of purity or menstruation).

Jabir bin Zayd (may Allah have mercy on him) said: A woman with irregular bleeding (mustahadah) observes her waiting period ('iddah) by aqra' (periods of purity or menstruation).

Tawus (may Allah have mercy on him) said: A woman with irregular bleeding (mustahadah) observes her waiting period ('iddah) by months.

Al-Hakam (may Allah have mercy on him) and Ata (may Allah have mercy on him) said: A woman with irregular bleeding (mustahadah) observes her waiting period ('iddah) by aqra' (periods of purity or menstruation).

Ata, al-Hakam and al-Hasan said: A woman with irregular bleeding (mustahadah) observes her waiting period ('iddah) by aqra' (periods of purity or menstruation).

Al-Zuhri (may Allah have mercy on him) said: A woman with irregular bleeding (mustahadah) observes her waiting period ('iddah) by aqra' (periods of purity or menstruation).

Ibrahim (may Allah have mercy on him) said: A woman with irregular bleeding (mustahadah) observes her waiting period ('iddah) by aqra' (periods of purity or menstruation).

Hammad (may Allah have mercy on him) said: If a man divorces his wife while she has irregular bleeding (istihadah), and she menstruates for the third time for the shortest duration she used to menstruate, her husband no longer has the right to take her back; but she does not take the ritual bath (ghusl) nor pray until the longest duration she used to menstruate has passed over her.

Sa'id bin al-Musayyib (may Allah have mercy on him) said: The waiting period ('iddah) of a woman with prolonged bleeding (istihadah) is one year.

Ikrimah (may Allah have mercy on him) said: A woman with prolonged bleeding (istihadah), and a woman whose menstruation has no regular pattern (sometimes it comes twice in one month and sometimes once in several months), her waiting period ('iddah) is three months.

He said: That was also the view of Qatadah.

Jabir bin Zayd (may Allah have mercy on him) said: Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) and Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) discussed the woman whose husband has gone missing. Both of them said that she will wait four years, then her husband's guardian will divorce her, then she will observe a waiting period of four months and ten days. Then the two of them discussed maintenance (nafaqah), and Sayyiduna Ibn Umar (may Allah be pleased with them both) said: The woman will receive maintenance from the man's wealth, because she has kept herself waiting on his account. Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: It is not so; that would harm the heirs. Rather, she will take it against him from his wealth: if he comes back, that wealth will be hers, and if he does not come back, the woman will get nothing.
