Narrated Ibn `Umar:
حَدَّثَنَا مُسَدَّدٌ ، حَدَّثَنَا يَحْيَى ، عَنْ عُبَيْدِ اللَّهِ ، أَخْبَرَنِي نَافِعٌ ، عَنِ ابْنِ عُمَرَ ، قَالَ لاَعَنَ النَّبِيُّ صلى الله عليه وسلم بَيْنَ رَجُلٍ وَامْرَأَةٍ مِنَ الأَنْصَارِ، وَفَرَّقَ بَيْنَهُمَا.
The Prophet (ﷺ) made an Ansari man and his wife carry out Lian, and then separated them by divorce.
