Narrated Um Salama:

The Prophet ﷺ said, "I am only a human being, and you people have disputes. May be some one amongst you can present his case in a more eloquent and convincing manner than the other, and I give my judgment in his favor according to what I hear. Beware! If ever I give (by error) somebody something of his brother's right then he should not take it as I have only, given him a piece of Fire." (See Hadith No. 638. Vol. 3)

حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، عَنْ سُفْيَانَ، عَنْ هِشَامٍ، عَنْ عُرْوَةَ، عَنْ زَيْنَبَ ابْنَةِ أُمِّ سَلَمَةَ، عَنْ أُمِّ سَلَمَةَ، عَنِ النَّبِيِّ ﷺ قَالَ " إِنَّمَا أَنَا بَشَرٌ، وَإِنَّكُمْ تَخْتَصِمُونَ، وَلَعَلَّ بَعْضَكُمْ أَنْ يَكُونَ أَلْحَنَ بِحُجَّتِهِ مِنْ بَعْضٍ، وَأَقْضِيَ لَهُ عَلَى نَحْوِ مَا أَسْمَعُ، فَمَنْ قَضَيْتُ لَهُ مِنْ حَقِّ أَخِيهِ شَيْئًا، فَلاَ يَأْخُذْ، فَإِنَّمَا أَقْطَعُ لَهُ قِطْعَةً مِنَ النَّارِ ".
