"Do you know 'Abdullah bin 'Umar?" He said: "Yes." He said: "He divorced his wife when she was menstruating, and 'Umar went to the Prophet and told him about that. He ordered him to take her back until she became pure," and I did not hear him adding anything to that. (Using translation from Nasāʾī 3559)
فَإِنَّهُ طَلَّقَ امْرَأَتَهُ حَائِضًا فَأَتَى عُمَرُ النَّبِيَّ ﷺ فَأَخْبَرَهُ الْخَبَرَ «فَأَمَرَهُ أَنْ يُرَاجِعَهَا حَتَّى تَطْهُرَ وَلَمْ أَسْمَعْهُ يَزِيدُ عَلَى هَذَا»
