حَدَّثَنَا هَنَّادٌ، حَدَّثَنَا حُسَيْنٌ الْجُعْفِيُّ، عَنْ زَائِدَةَ، عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ حَنَشٍ، عَنْ عَلِيٍّ، قَالَ قَالَ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم " إِذَا تَقَاضَى إِلَيْكَ رَجُلاَنِ فَلاَ تَقْضِ لِلأَوَّلِ حَتَّى تَسْمَعَ كَلاَمَ الآخَرِ فَسَوْفَ تَدْرِي كَيْفَ تَقْضِي " . قَالَ عَلِيٌّ فَمَا زِلْتُ قَاضِيًا بَعْدُ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ .

Ḥanash reported that ʿAlī said: “The Messenger of Allah told me: ‘When two people bring a case to you, do not judge in favor of the first until you have heard what the other has to say. Then you will know how to judge.’” ʿAlī said: “I continued to serve as a judge after that.” Abū ʿĪsā said: This is a ḥasan hadith.
