Regarding Li'an (Mutual Cursing)
حَدَّثَنَا مُسَدَّدٌ، وَوَهْبُ بْنُ بَيَانٍ، وَأَحْمَدُ بْنُ عَمْرِو بْنِ السَّرْحِ، وَعَمْرُو بْنُ عُثْمَانَ، قَالُوا حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ سَهْلِ بْنِ سَعْدٍ، قَالَ مُسَدَّدٌ قَالَ شَهِدْتُ الْمُتَلاَعِنَيْنِ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم وَأَنَا ابْنُ خَمْسَ عَشْرَةَ فَفَرَّقَ بَيْنَهُمَا رَسُولُ اللَّهِ صلى الله عليه وسلم حِينَ تَلاَعَنَا . وَتَمَّ حَدِيثُ مُسَدَّدٍ . وَقَالَ الآخَرُونَ إِنَّهُ شَهِدَ النَّبِيَّ صلى الله عليه وسلم فَرَّقَ بَيْنَ الْمُتَلاَعِنَيْنِ فَقَالَ الرَّجُلُ كَذَبْتُ عَلَيْهَا يَا رَسُولَ اللَّهِ إِنْ أَمْسَكْتُهَا - لَمْ يَقُلْ بَعْضُهُمْ عَلَيْهَا - قَالَ أَبُو دَاوُدَ لَمْ يُتَابِعِ ابْنَ عُيَيْنَةَ أَحَدٌ عَلَى أَنَّهُ فَرَّقَ بَيْنَ الْمُتَلاَعِنَيْنِ .
Sahl bin Sa’ad said “The version of Musaddad has “I witnessed the invoking of curses by the two spouses during the life time of the Messenger of Allah(ﷺ) when I was fifteen years old. When they finished invoking curses, the Messenger of Allah(ﷺ) separated them from each other. Here ends the version of Musaddad. Others said “He was present when the Prophet (ﷺ) separated the spouses who invoked curses on each other. The man (Sahl) said “I shall have lied against her, Apostle of Allaah(ﷺ) if I keep her. Abu Dawud said “Some narrators did not mention the word ‘alaiha(against her).” Abu Dawud said “No one supported Ibn ‘Uyainah that he separated the spouses who invoked curses.”
