حَدَّثَنَا سُفْيَانُ، عَنْ أَيُّوبَ، عَنْ سَعِيدٍ
قَالَ قُلْتُ لِابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُ رَجُلٌ لَاعَنَ امْرَأَتَهُ فَقَالَ فَرَّقَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَيْنَهُمَا وَذَكَرَ الْحَدِيثَ
I said to IbnʼUmar (رضي الله عنه): What about a man who engaged in lian with his wife? He said: The Messenger of Allah (sallallahu alayhi wa sallam) would separate them – and he mentioned the hadeeth.
