Sayyiduna Abdullah bin Umar (may Allah be pleased with them) divorced his wife (Amina bint Ghafar) during the time of the Messenger of Allah (peace and blessings be upon him) while she was in her menstrual period. Sayyiduna Umar bin Khattab (may Allah be pleased with him) asked the Messenger of Allah (peace and blessings be upon him) about this matter, so he said: Tell him to take his wife back and then keep her in his marriage until her menstruation ends, then her menstruation comes again and ends. Then, if he wishes, he may keep his wife in his marriage, and if he wishes, he may divorce her (but the divorce should be in that period of purity) before having intercourse with her. This is the period of purity in which Allah Almighty has commanded to divorce women.
