The Prophet ﷺ said to me. “When two disputants come to you, do not listen to the words of the first one until you have also listened to the words of the other, then you will know how to judge.ʿ And ‘Ali ؓ said: Since then I have continued to be a good judge.
لِي النَّبِيُّ ﷺ إِذَا تَقَدَّمَ إِلَيْكَ خَصْمَانِ فَلا تَسْمَعْ كَلامَ الْأَوَّلِ حَتَّى تَسْمَعَ كَلامَ الْآخَرِ فَسَوْفَ تَرَى كَيْفَ تَقْضِي قَالَ فَقَالَ عَلِيٌّ فَمَا زِلْتُ بَعْدَ ذَلِكَ قَاضِيًا
