Narrated Abu Huraira and Zaid bin Khalid:

We were with the Prophet when he said (to two men), "I shall judge between you according to Allah's Book (Laws)."

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا الزُّهْرِيُّ، عَنْ عُبَيْدِ اللَّهِ، عَنْ أَبِي هُرَيْرَةَ، وَزَيْدِ بْنِ خَالِدٍ، قَالاَ كُنَّا عِنْدَ النَّبِيِّ ﷺ فَقَالَ
" لأَقْضِيَنَّ بَيْنَكُمَا بِكِتَابِ اللَّهِ ".
