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.
