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