In-book no 3395أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ السَّرَخْسِيُّ، قَالَ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ الْقَطَّانُ، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ، قَالَ أَخْبَرَنِي نَافِعٌ، عَنْ عَبْدِ اللَّهِ، أَنَّهُ طَلَّقَ امْرَأَتَهُ وَهِيَ حَائِضٌ فَاسْتَفْتَى عُمَرُ رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَ إِنَّ عَبْدَ اللَّهِ طَلَّقَ امْرَأَتَهُ وَهِيَ حَائِضٌ فَقَالَ " مُرْ عَبْدَ اللَّهِ فَلْيُرَاجِعْهَا ثُمَّ يَدَعْهَا حَتَّى تَطْهُرَ مِنْ حَيْضَتِهَا هَذِهِ ثُمَّ تَحِيضَ حَيْضَةً أُخْرَى فَإِذَا طَهُرَتْ فَإِنْ شَاءَ فَلْيُفَارِقْهَا قَبْلَ أَنْ يُجَامِعَهَا وَإِنْ شَاءَ فَلْيُمْسِكْهَا فَإِنَّهَا الْعِدَّةُ الَّتِي أَمَرَ اللَّهُ عَزَّ وَجَلَّ أَنْ تُطَلَّقَ لَهَا النِّسَاءُ " .
Nafi' narrated from 'Abdullah, that he divorced his wife while she was menstruating. 'Umar asked the Messenger of Allah about that and said: "Abdullah has divorced his wife while she was menstruating." He said: "Tell 'Abdullah to take her back, then leave her until she becomes pure from this menstrual period, then menstruates again, then when she becomes pure again, if he wishes he may separate from her before having intercourse with her, or if he wishes he may keep her. This is the time when Allah, the Mighty and Sublime, has stated that women may be divorced."
