(5) باب مَا جَاءَ فِي الْقَاضِي لاَ يَقْضِي بَيْنَ الْخَصْمَيْنِ حَتَّى يَسْمَعَ كَلاَمَهُمَا .
'Ali narrated:
"The Messenger of Allah (ﷺ) said to me: 'When two men come to you seeking judgement, do not judge for the first until you have heard the statement of the other. Soon you will know how to judge.'" 'Ali said: "I did not err since then."
