"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."  

أَنَّهُ طَلَّقَ امْرَأَتَهُ وَهِيَ حَائِضٌ فَاسْتَفْتَى عُمَرُ رَسُولَ اللَّهِ ﷺ 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 ﷻ أَنْ تُطَلَّقَ لَهَا النِّسَاءُ  

"Tell 'Abdullah to take her back, then, when she has performed Ghusl, let him leave her alone, until she menstruates (again). Then, when she performs Ghusl following that second period, he should not touch her until he divorces her. And if he wants to keep her, then let him keep her. That is the time when Allah has stated that women may be divorced."  

أَنَّهُ طَلَّقَ امْرَأَتَهُ وَهِيَ حَائِضٌ تَطْلِيقَةً فَانْطَلَقَ عُمَرُ فَأَخْبَرَ النَّبِيَّ ﷺ بِذَلِكَ فَقَالَ لَهُ النَّبِيُّ ﷺ مُرْ عَبْدَ اللَّهِ فَلْيُرَاجِعْهَا فَإِذَا اغْتَسَلَتْ فَلْيَتْرُكْهَا حَتَّى تَحِيضَ فَإِذَا اغْتَسَلَتْ مِنْ حَيْضَتِهَا الأُخْرَى فَلاَ يَمَسَّهَا حَتَّى يُطَلِّقَهَا فَإِنْ شَاءَ أَنْ يُمْسِكَهَا فَلْيُمْسِكْهَا فَإِنَّهَا الْعِدَّةُ الَّتِي أَمَرَ اللَّهُ ﷻ أَنْ تُطَلَّقَ لَهَا النِّسَاءُ  

"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 وَهِيَ حَائِضٌ فَأَتَى عُمَرُ النَّبِيَّ ﷺ فَاسْتَفْتَاهُ فَقَالَ مُرْ عَبْدَ اللهِ فَلْيُرَاجِعْهَا حَتَّى تَطْهُرَ مِنْحَيْضَتِهَا هَذِهِ ثُمَّ تَحِيضَ حَيْضَةً أُخْرَى فَإِذَا طَهُرَتْ فَلْيُفَارِقْهَا قَبْلَ أَنْ يُجَامِعَهَا أَوْ لِيُمْسِكْهَا فَإِنَّهَا الْعِدَّةُ الَّتِي أُمِرَ أَنْ تُطَلَّقَ لَهَا النِّسَاءُ  

[Machine] He divorced his wife while she was menstruating, and he mentioned that to Umar. Umar then went to the Messenger of Allah ﷺ and informed him. So the Messenger of Allah ﷺ said: "Let him keep her until she menstruates again, other than this menstruation, then she should purify herself. If it appears to him that he should divorce her, then he should divorce her as Allah commanded. And if it appears to him that he should keep her, then he should keep her."  

أَنَّهُ طَلَّقَ امْرَأَتَهُ وَهِيَ حَائِضٌ فَذَكَرَ ذَلِكَ إِلَى عُمَرَ فَانْطَلَقَ عُمَرُ إِلَى رَسُولِ اللهِ ﷺ فَأَخْبَرَهُ فَقَالَ رَسُولُ اللهِ ﷺ لِيُمْسِكْهَا حَتَّى تَحِيضَ غَيْرَ هَذِهِ الْحَيْضَةِ ثُمَّ تَطْهُرَ فَإِنْ بَدَا لَهُ أَنْ يُطَلِّقَهَا فَلْيُطَلِّقْهَا كَمَا أَمَرَهُ اللهُ ﷻ وَإِنْ بَدَا لَهُ أَنْ يُمْسِكَهَا فَلْيُمْسِكْهَا  

"عَنِ ابْنِ عُمرَ أَنَّهُ طَلَّقَ امْرأَتَهُ وَهِىَ حَائِضٌ، فَاسْتَفْتَى عُمَرُ رَسُولَ الله ﷺ فَقَالَ: مُرْ عَبْدَ الله فَلْيُرَاجِعهَا ثُم ليُمْسِكْهَا حَتَّى تَطْهُرَ، ثُمَّ تَحِيضَ فَتَطْهُرَ، فَإِنْ بَدَا لَهُ أَنْ يُطَلِّقَهَا فَليُطَلِّقَهَا طَاهِرًا قَبْلَ أَنْ يَمسَّهَا، فَتِلْكَ الْعِدّةُ الَّتِى أَمَرَ الله أَنْ يُطلّقَ لَهَا النَّسَاء".
