The Messenger of Allah [SAW] said: "You refer your disputes to me, but I am only human, and some of you may be more eloquent in arguing their case than others. If I pass judgment in favor of one of you, against his brother's rights, let him not take it, for it is a piece of fire that I am giving him." (Using translation from Nasāʾī 5401)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «إِنَّكُمْ تَخْتَصِمُونَ إِلَيَّ وَإِنَّمَا أَنَا بَشَرٌ وَلَعَلَّ بَعْضَكُمْ أَلْحَنُ بِحُجَّتِهِ مِنْ بَعْضٍ فَمَنْ قَضَيْتُ لَهُ مِنْ حَقِّ أَخِيهِ شَيْئًا فَلَا يَأْخُذْهُ فَإِنَّمَا أَقْطَعُهُ بِهِ قِطْعَةً مِنَ النَّارِ»
