Chapter on the Divorce of a Woman Who Has Not Reached Menstruation, One Reached Menopausal Age, One with Irregular Menstruation, and One with Uncertain Menstruation

Al-Hasan ibn Mahbub narrated from Aban ibn Uthman, from Al-Halabi, from Abu Abdullah عليه السلام who said: "The waiting period ('iddah) for a woman who does not menstruate, for a woman experiencing continuous irregular bleeding (mustahadah) who does not become pure, and for a young girl who has reached menopause is three months. As for a woman whose menstruation is regular, her waiting period is three menstrual cycles."
