Ibn Umar reported: He divorced his wife in the time of the Messenger of Allah, peace and blessings be upon him, while she menstruating. Umar ibn al-Khattab asked the Prophet about that and he said, “Order him to return her. Let him leave her alone until she becomes pure, then menstruates, and then is pure again. If he wishes, he may keep her or divorce her before he is intimate with her. That is the waiting period Allah has commanded for divorcing women.” (65:1)

Al-Shafi’i said, “Allah Almighty has commanded adherence to good conduct, to release in the best manner, and He has prohibited harm. Divorcing a menstruating woman is harmful.”

عَنْ ابْنِ عُمَرَ أَنَّهُ طَلَّقَ امْرَأَتَهُ وَهِيَ حَائِضٌ فِي عَهْدِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَسَأَلَ عُمَرُ بْنُ الْخَطَّابِ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ ذَلِكَ فَقَالَ لَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مُرْهُ فَلْيُرَاجِعْهَا ثُمَّ لِيَتْرُكْهَا حَتَّى تَطْهُرَ ثُمَّ تَحِيضَ ثُمَّ تَطْهُرَ ثُمَّ إِنْ شَاءَ أَمْسَكَ بَعْدُ وَإِنْ شَاءَ طَلَّقَ قَبْلَ أَنْ يَمَسَّ فَتِلْكَ الْعِدَّةُ الَّتِي أَمَرَ اللَّهُ عَزَّ وَجَلَّ أَنْ يُطَلَّقَ لَهَا النِّسَاءُ

قال الشافعي وَقَدْ أَمَرَ اللَّهُ تَعَالَى بِالْإِمْسَاكِ بِالْمَعْرُوفِ وَالتَّسْرِيحِ بِالْإِحْسَانِ وَنَهَى عَنْ الضَّرَرِ وَطَلَاقُ الْحَائِضِ ضَرَرٌ
