Narrated Sahl bin Sa`d:
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.
