Whoever gave judgements of Li'an in the mosque

Narrated Sahl bin Sa`d:

I witnessed a husband and a wife who were involved in a case of Lian. Then (the judgment of) divorce was passed. I was fifteen years of age, at that time.

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا سُفْيَانُ، قَالَ الزُّهْرِيُّ عَنْ سَهْلِ بْنِ سَعْدٍ، قَالَ شَهِدْتُ الْمُتَلاَعِنَيْنِ وَأَنَا ابْنُ خَمْسَ، عَشْرَةَ فُرِّقَ بَيْنَهُمَا‏.‏

Narrated Sahl:

(the brother of Bani Sa`ida) A man from the Ansar came to the Prophet (ﷺ) and said, "If a man finds another man sleeping with his wife, should he kill him?" That man and his wife then did Lian in the mosque while I was present.

حَدَّثَنَا يَحْيَى، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا ابْنُ جُرَيْجٍ، أَخْبَرَنِي ابْنُ شِهَابٍ، عَنْ سَهْلٍ، أَخِي بَنِي سَاعِدَةَ أَنَّ رَجُلاً، مِنَ الأَنْصَارِ جَاءَ إِلَى النَّبِيِّ صلى الله عليه وسلم فَقَالَ أَرَأَيْتَ رَجُلاً وَجَدَ مَعَ امْرَأَتِهِ رَجُلاً، أَيَقْتُلُهُ فَتَلاَعَنَا فِي الْمَسْجِدِ وَأَنَا شَاهِدٌ‏.‏
