It was narrated that Yunus bin Jubair said:

"I asked Ibn 'Umar about a man who divorced his wife while she was menstruating. He said: 'Do you know 'Abdullah bin 'Umar?' He divorced his wife while she was menstruating, and 'Umar asked the Prophet about that, and he told him to take her back, then wait for the right time. I said to him: 'Was that divorce counted?' He said: 'Be quiet! What do you think if some becomes helpless and behaves foolishly?'"

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ أَيُّوبَ، عَنْ مُحَمَّدٍ، عَنْ يُونُسَ بْنِ جُبَيْرٍ، قَالَ سَأَلْتُ ابْنَ عُمَرَ عَنْ رَجُلٍ، طَلَّقَ امْرَأَتَهُ وَهِيَ حَائِضٌ فَقَالَ هَلْ تَعْرِفُ عَبْدَ اللَّهِ بْنَ عُمَرَ فَإِنَّهُ طَلَّقَ امْرَأَتَهُ وَهِيَ حَائِضٌ فَسَأَلَ عُمَرُ النَّبِيَّ ﷺ فَأَمَرَهُ أَنْ يُرَاجِعَهَا ثُمَّ يَسْتَقْبِلَ عِدَّتَهَا . فَقُلْتُ لَهُ فَيَعْتَدُّ بِتِلْكَ التَّطْلِيقَةِ فَقَالَ مَهْ أَرَأَيْتَ إِنْ عَجَزَ وَاسْتَحْمَقَ .
