Narrated Um Salama:

Allah's Apostle ﷺ said, "I am only a human being, and you people (opponents) come to me with your cases;
and it may be that one of you can present his case eloquently in a more convincing way than the other, and I give my verdict according to what I hear. So if ever I judge (by error) and give the right of a brother to his other (brother) then he (the latter) should not take it, for I am giving him only a piece of Fire." (See Hadith No. 638, Vol. 3).

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ زَيْنَبَ ابْنَةِ أَبِي سَلَمَةَ، عَنْ أُمِّ سَلَمَةَ ـ رضى الله عنها ـ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " إِنَّمَا أَنَا بَشَرٌ، وَإِنَّكُمْ تَخْتَصِمُونَ إِلَىَّ، وَلَعَلَّ بَعْضَكُمْ أَنْ يَكُونَ أَلْحَنَ بِحُجَّتِهِ مِنْ بَعْضٍ فَأَقْضِي نَحْوَ مَا أَسْمَعُ، فَمَنْ قَضَيْتُ لَهُ بِحَقِّ أَخِيهِ شَيْئًا فَلاَ يَأْخُذْهُ، فَإِنَّمَا أَقْطَعُ لَهُ قِطْعَةً مِنَ النَّارِ ".
