وَحَدَّثَنِي هَارُونُ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا حَجَّاجُ بْنُ مُحَمَّدٍ، قَالَ قَالَ ابْنُ جُرَيْجٍ أَخْبَرَنِي أَبُو الزُّبَيْرِ، أَنَّهُ سَمِعَ عَبْدَ الرَّحْمَنِ بْنَ أَيْمَنَ، مَوْلَى عَزَّةَ يَسْأَلُ ابْنَ عُمَرَ وَأَبُو الزُّبَيْرِ يَسْمَعُ ذَلِكَ كَيْفَ تَرَى فِي رَجُلٍ طَلَّقَ امْرَأَتَهُ حَائِضًا فَقَالَ طَلَّقَ ابْنُ عُمَرَ امْرَأَتَهُ وَهْىَ حَائِضٌ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَسَأَلَ عُمَرُ رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَ إِنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ طَلَّقَ امْرَأَتَهُ وَهْىَ حَائِضٌ ‏.‏ فَقَالَ لَهُ النَّبِيُّ صلى الله عليه وسلم ‏"‏ لِيُرَاجِعْهَا ‏"‏ ‏.‏ فَرَدَّهَا وَقَالَ ‏"‏ إِذَا طَهَرَتْ فَلْيُطَلِّقْ أَوْ لِيُمْسِكْ ‏"‏ ‏.‏ قَالَ ابْنُ عُمَرَ وَقَرَأَ النَّبِيُّ صلى الله عليه وسلم يَا أَيُّهَا النَّبِيُّ إِذَا طَلَّقْتُمُ النِّسَاءَ فَطَلِّقُوهُنَّ فِي قُبُلِ عِدَّتِهِنَّ ‏.‏

What is your opinion about the person who divorced his wife in the state of menses? Thereupon he said: Ibn Umar (Allah be pleased with them) divorced his wife during the lifetime of Allah's Messenger (ﷺ) while she was in the state of menses. Upon this Allah's Messenger (ﷺ) told him to take her back and so he took her back and he (further) said: When she is pure, then either divorce her or retain her. Ibn 'Umar (Allah be pleased with them) said that Allah's Apostle (ﷺ) then recited this verse:" O Apostle, when you divorce women, divorce them at the commencement of their prescribed period" (Ixv 1).
