Mishkat al-Masabih 18 The Offices of Commander and Qadi كتاب الإمارة والقضاء 97

وَعَنْ أُمِّ سَلَمَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِنَّمَا أَنَا بَشَرٌ وَإِنَّكُمْ تَخْتَصِمُونَ إِلَيَّ وَلَعَلَّ بَعْضَكُمْ أَنْ يَكُونَ أَلْحَنَ بِحُجَّتِهِ مِنْ بَعْضٍ فَأَقْضِي لَهُ عَلَى نَحْوِ مَا أَسْمَعُ مِنْهُ فَمَنْ قَضَيْتُ لَهُ بِشَيْءٍ مِنْ حَقِّ أَخِيهِ فَلَا يَأْخُذَنَّهُ فَإِنَّمَا أَقْطَعُ لَهُ قِطْعَةً مِنَ النَّار»

Umm Salama reported God’s Messenger as saying, “I am only a human being and you bring your disputes to me, some perhaps being more eloquent in their plea than others, so that I give judgment on their behalf according to what I hear from them. Therefore whatever I decide for anyone which by right belongs to his brother he must not take, for I am granting him only a portion of hell.” (Bukhari and Muslim.)
