I divorced my wife while she was in the state of menses. 'Umar (Allah he pleased wish him) came toAllah's Apostle ﷺ and made mention of that to him, whereupon Allah's Apostle ﷺ told that be should take her back, and when she is pure he may divorce her. if he would so wish. I (one of the narrators) said to Ibn 'Umar (Allah be pleased with them): Did you count (this pronouncement of divorce) in her case? He said: What (after all) prevents him from doing so? Do you find him (Ibn Umar) either helpless or foolish?
سَمِعْتُ ابْنَ عُمَرَ يَقُولُ طَلَّقْتُ امْرَأَتِي وَهْىَ حَائِضٌ فَأَتَى عُمَرُ النَّبِيَّ ﷺ فَذَكَرَ ذَلِكَ لَهُ فَقَالَ النَّبِيُّ ﷺ لِيُرَاجِعْهَا فَإِذَا طَهَرَتْ فَإِنْ شَاءَ فَلْيُطَلِّقْهَا قَالَ فَقُلْتُ لاِبْنِ عُمَرَ أَفَاحْتَسَبْتَ بِهَا قَالَ مَا يَمْنَعُهُ أَرَأَيْتَ إِنْ عَجَزَ وَاسْتَحْمَقَ
