حَدَّثَنَا إِسْمَاعِيلُ حَدَّثَنَا أَيُّوبُ عَنْ نَافِعٍ أَنَّ ابْنَ عُمَرَ طَلَّقَ امْرَأَتَهُ تَطْلِيقَةً وَهِيَ حَائِضٌ فَسَأَلَ عُمَرُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَأَمَرَهُ أَنْ يَرْجِعَهَا ثُمَّ يُمْهِلَهَا حَتَّى تَحِيضَ حَيْضَةً أُخْرَى ثُمَّ يُمْهِلَهَا حَتَّى تَطْهُرَ ثُمَّ يُطَلِّقَهَا قَبْلَ أَنْ يَمَسَّهَا قَالَ وَتِلْكَ الْعِدَّةُ الَّتِي أَمَرَ اللَّهُ عَزَّ وَجَلَّ أَنْ يُطَلَّقَ لَهَا النِّسَاءُ فَكَانَ ابْنُ عُمَرَ إِذَا سُئِلَ عَنْ الرَّجُلِ يُطَلِّقُ امْرَأَتَهُ وَهِيَ حَائِضٌ فَيَقُولُ أَمَّا أَنَا فَطَلَّقْتُهَا وَاحِدَةً أَوْ اثْنَتَيْنِ ثُمَّ إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَمَرَهُ أَنْ يُرْجِعَهَا ثُمَّ يُمْهِلَهَا حَتَّى تَحِيضَ حَيْضَةً أُخْرَى ثُمَّ يُمْهِلَهَا حَتَّى تَطْهُرَ ثُمَّ يُطَلِّقَهَا قَبْلَ أَنْ يَمَسَّهَا وَأَمَّا أَنْتَ طَلَّقْتَهَا ثَلَاثًا فَقَدْ عَصَيْتَ اللَّهَ بِمَا أَمَرَكَ بِهِ مِنْ طَلَاقِ امْرَأَتِكَ وَبَانَتْ مِنْكَ
مسند امام احمد بن حنبل · Hadith 4500
It was narrated from Naafi’ That the Umar divorced his wife once (one talaaq) when she was menstruating. 'Umar asked the prophet (PBUH) (about that) and he instructed htm to take her back hen wait until she had gone rough another menstrual cycle then to wait until she became pure, then to divorce her before being intimate with her. He said: “That is the iddah (prescribed period) that Allah (PBUH) has enjoined for the divorce of women." If lbn 'Umar was asked about a man who divorced his wife when die was menstruating, he would say: As for me, I divorced her once or twice, then the Messenger of Allah (PBUH) instructed him to take her back then wait until she had gore through another menstrual cycle then to wait until she became pure, then to divorce her before having been intimate with her. But as for you, you have divorced her three times, so you have disobeyed Allah in what He enjoined upon you with regard to divorcing your wife; she is irrevocably divorced from you.
