44) باب الْقَضَاءِ وَاللِّعَانِ فِي الْمَسْجِدِ بَيْنَ الرِّجَالِ وَالنِّسَاءِ

حَدَّثَنَا يَحْيَى، قَالَ أَخْبَرَنَا عَبْدُ الرَّزَّاقِ، قَالَ أَخْبَرَنَا ابْنُ جُرَيْجٍ، قَالَ أَخْبَرَنِي ابْنُ شِهَابٍ، عَنْ سَهْلِ بْنِ سَعْدٍ، أَنَّ رَجُلاً، قَالَ يَا رَسُولَ اللَّهِ، أَرَأَيْتَ رَجُلاً وَجَدَ مَعَ امْرَأَتِهِ رَجُلاً أَيَقْتُلُهُ فَتَلاَعَنَا فِي الْمَسْجِدِ وَأَنَا شَاهِدٌ‏.‏
