What is your opinion about the person who divorced his wife in the state of menses? Thereupon he said: Ibn Umar (Allah be pleased with them) divorced his wife during the lifetime of Messenger of Allah ﷺ while she was in the state of menses. Upon this Messenger of Allah ﷺ told him to take her back and so he took her back and he (further) said: When she is pure, then either divorce her or retain her. Ibn 'Umar (Allah be pleased with them) said that Allah's Apostle ﷺ then recited this verse:" O Apostle, when you divorce women, divorce them at the commencement of their prescribed period" (Ixv 1).
