أَخْبَرَنِي زِيَادُ بْنُ أَيُّوبَ قَالَ حَدَّثَنَا هُشَيْمٌ قَالَ أَخْبَرَنَا أَبُو بِشْرٍ عَنْ سَعِيدِ بْنِ جُبَيْرٍ عَنْ ابْنِ عُمَرَ أَنَّهُ طَلَّقَ امْرَأَتَهُ وَهِيَ حَائِضٌ فَرَدَّهَا عَلَيْهِ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ حَتَّی طَلَّقَهَا وَهِيَ طَاهِرٌ
سنن نسائی · Hadith 3430
It was narrated from ‘Abdullah that he issued a divorce to his wife when she was menstruating. So ‘Umar went to inform the Prophet صلی اللہ علیہ وآلہ وسلم about that. The Prophet صلی اللہ علیہ وآلہ وسلم said to him: “Tell ‘Abdullah to take her back, then, when she has performed Ghusl, let him leave her alone, until she menstruates (again). Then, when she performs Ghusl following that second period, he should not touch her until he divorces her. And if he wants to keep her, then let him keep her. That is the time when Allah has stated that women may be divorced.” (Sahih)
