[Machine] I witnessed the two cursed ones in the presence of the Prophet ﷺ when I was fifteen years old, then he narrated the story.  

البيهقي:١٥٣٣٨أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ نا أَبُو الْعَبَّاسِ مُحَمَّدُ بْنُ يَعْقُوبَ أنا الرَّبِيعُ بْنُ سُلَيْمَانَ أنا الشَّافِعِيُّ أنا سُفْيَانُ عَنِ ابْنِ شِهَابٍ عَنْ سَهْلِ بْنِ سَعْدٍ قَالَ

شَهِدْتُ الْمُتَلَاعِنَيْنِ عِنْدَ النَّبِيِّ ﷺ وَأَنَا ابْنُ خَمْسَ عَشْرَةَ سَنَةً ثُمَّ سَاقَ الْحَدِيثَ
