حَدَّثَنَا يَحْيَى ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ ، أَخْبَرَنَا ابْنُ جُرَيْجٍ ، أَخْبَرَنِي ابْنُ شِهَابٍ ، عَنْ سَهْلٍ أَخِي بَنِي سَاعِدَةَ ، أَنَّ رَجُلًا مِنَ الْأَنْصَارِ جَاءَ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، فَقَالَ : " أَرَأَيْتَ رَجُلًا وَجَدَ مَعَ امْرَأَتِهِ رَجُلًا أَيَقْتُلُهُ ؟ ، فَتَلَاعَنَا فِي الْمَسْجِدِ وَأَنَا شَاهِدٌ .
