ذِكْرُ الْأَمْرِ لِمَنْ أَرَادَ أَنْ يُطَلِّقَ امْرَأَتَهُ أَنْ يُطَلِّقَهَا فِي طُهْرِهَا لَا فِي حَيْضِهَا
"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." (Using translation from Nasāʾī 3389)
أَنَّهُ طَلَّقَ امْرَأَتَهُ تَطْلِيقَةً وَهِيَ حَائِضٌ فَاسْتَفْتَى عُمَرُ رَسُولَ اللَّهِ ﷺ فَقَالَ إِنَّ عَبْدَ اللَّهِ طَلَّقَ امْرَأَتَهُ وَهِيَ حَائِضٌ فَقَالَ «مُرْ عَبْدَ اللَّهِ فَلْيُرَاجِعْهَا ثُمَّ لِيُمْسِكْهَا حَتَّى تَطْهُرَ مِنْ حَيْضَتِهَا هَذِهِ فَإِذَا حَاضَتْ حَيْضَةً أُخْرَى فَطَهُرَتْ فَإِنْ شَاءَ فَلْيُطَلِّقْهَا قَبْلَ أَنْ يُجَامِعَهَا وَإِنْ شَاءَ فَلْيُمْسِكْهَا»
