حَدَّثَنَا عَبْد اللَّهِ حَدَّثَنَا مُحَمَّدُ بْنُ سُلَيْمَانَ لُوَيْنٌ وَحَدَّثَنَا مُحَمَّدُ بْنُ جَابِرٍ عَنْ سِمَاكٍ عَنْ حَنَشٍ عَنْ عَلِيِّ بْنِ أَبِي طَالِبٍ رَضِيَ اللَّهُ عَنْهُ قَالَ بَعَثَنِي النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَاضِيًا إِلَى الْيَمَنِ فَذَكَرَ الْحَدِيثَ قَالَ إِنَّ اللَّهَ مُثَبِّتٌ قَلْبَكَ وَهَادٍ فُؤَادَكَ فَذَكَرَ الْحَدِيثَ
مسند امام احمد بن حنبل · Hadith 1282
It was narrated that 'Ali (RA) said: The Prophet (PBUH) sent me to Yemen as a judge. I said: Are you sending me to people when i am young and have no knowledge of judging? He placed his hand on my chest and said: "May Allah make you steadfast and help you to get it right. If two disputants come to you, do not pass judgement in favour of the first one until you listen to what the other one has to say. That is more helpful and will enable you to reach the correct verdict." Since then I have become a (good) judge.
