Abdullah bin Umar said that he divorced his wife while she was menstruating during the time of the Messenger of Allah صلی اللہ علیہ وسلم. So Umar bin Al Khattab asked the Messenger of Allah صلی اللہ علیہ وسلم about this matter. The Messenger of Allah صلی اللہ علیہ وسلم said “Order him, he must take her back and keep her back till she is purified, then has another menstrual period and is purified. Thereafter if he desires he may divorce her before having intercourse with her, for that is the period of waiting which Allaah the Glorified has commanded for the divorce of women. ”
