حَدَّثَنَا عَبْدُ الرَّحْمَنِ عَنْ مَالِكٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّهُ طَلَّقَ امْرَأَتَهُ وَهِيَ حَائِضٌ فَسَأَلَ عُمَرُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ مُرْهُ فَلْيُرَاجِعْهَا ثُمَّ يُمْسِكْهَا حَتَّى تَطْهُرَ ثُمَّ تَحِيضَ ثُمَّ تَطْهُرَ ثُمَّ إِنْ شَاءَ طَلَّقَهَا وَإِنْ شَاءَ أَمْسَكَهَا فَتِلْكَ الْعِدَّةُ الَّتِي أَمَرَ اللَّهُ أَنْ يُطَلَّقَ لَهَا النِّسَاءُ
مسند امام احمد بن حنبل · Hadith 5299
It was narrated from Ibn 'Umar that he divorced his wife when she was menstruating, and 'Umar asked the Prophet (PBUH) about that. He said: "Tell him to take her back and keep her until she has become pure, then menstruated again, then become pure again. Then if he wishes he may divorce her, or if he wishes he may keep her. That is the iddah (prescribed periods) at which Allah has enjoined the divorce of women."
