Chapter: The prohibition of divorcing a menstruating woman without her consent; If a man breaks this rule, it still counts as a divorce, and he should be ordered to take her back
Ayyub reported a hadith like this with the same chain of narrators and he said: Umar (Allah be pleased with him) asked Allah's Apostle ( صلی اللہ علیہ وسلم ) about it and he commanded him that he should take her back until she is divorced in the state of purity without having a sexual intercourse with her, and said: Divorce her in the beginning of her 'Idda or her 'Idda commences.
