You bring to me, for (judgment) your disputes, some of you perhaps being more eloquent in their plea than others, so I give judgment on their behalf according to what I hear from them. (Bear in mind, in my judgment) if I slice off anything for him from the right of his brother, he should not accept that, for I sliced off for him a portion from the Hell.  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّكُمْ تَخْتَصِمُونَ إِلَىَّ وَلَعَلَّ بَعْضَكُمْ أَنْ يَكُونَ أَلْحَنَ بِحُجَّتِهِ مِنْ بَعْضٍ فَأَقْضِي لَهُ عَلَى نَحْوٍ مِمَّا أَسْمَعُ مِنْهُ فَمَنْ قَطَعْتُ لَهُ مِنْ حَقِّ أَخِيهِ شَيْئًا فَلاَ يَأْخُذْهُ فَإِنَّمَا أَقْطَعُ لَهُ بِهِ قِطْعَةً مِنَ النَّارِ  

This hadith has been narrated on the authority of Hisham with the same chain of transmitters.  

عَنْ هِشَامٍ بِهَذَا الإِسْنَادِ مِثْلَهُ  

I am a human being and the claimants bring to me (the dispute) and perhaps some of them are more eloquent than the others. I judge him to be on the right, and thus decide in his favcur. So he whom I, by my judgment, (give the undue share) out of the right of a Muslim,. I give him a portion of Fire; he may burden himself with it or abandon it.  

عَنْ أُمِّ سَلَمَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّ رَسُولَ اللَّهِ ﷺ سَمِعَ جَلَبَةَ خَصْمٍ بِبَابِ حُجْرَتِهِ فَخَرَجَ إِلَيْهِمْ فَقَالَ إِنَّمَا أَنَا بَشَرٌ وَإِنَّهُ يَأْتِينِي الْخَصْمُ فَلَعَلَّ بَعْضَهُمْ أَنْ يَكُونَ أَبْلَغَ مِنْ بَعْضٍ فَأَحْسِبُ أَنَّهُ صَادِقٌ فَأَقْضِي لَهُ فَمَنْ قَضَيْتُ لَهُ بِحَقِّ مُسْلِمٍ فَإِنَّمَا هِيَ قِطْعَةٌ مِنَ النَّارِ فَلْيَحْمِلْهَا أَوْ يَذَرْهَا  

This hadith has been transmitted on the authority of Ma'mar with a slight variation of words.  

عَنِ الزُّهْرِيِّ بِهَذَا الإِسْنَادِ نَحْوَ حَدِيثِ يُونُسَ وَفِي حَدِيثِ مَعْمَرٍ قَالَتْ سَمِعَ النَّبِيُّ ﷺ لَجَبَةَ خَصْمٍ بِبَابِ أُمِّ سَلَمَةَ
