Jami` at-Tirmidhi, Book 15, Hadith 19 (In-Book) ⓘ
Umm Salamah narrated that the Messenger of Allah said: "Indeed you come to me with your disputes, and I am only a human being, perhaps one of you is more eloquent at presenting his argument than the other. If I judge for one of you, giving him something from the rights of his brother, then it is only a piece of the Fire that I am giving him, so do not take anything from it."
حَدَّثَنَا هَارُونُ بْنُ إِسْحَاقَ الْهَمْدَانِيُّ، حَدَّثَنَا عَبْدَةُ بْنُ سُلَيْمَانَ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ زَيْنَبَ بِنْتِ أُمِّ سَلَمَةَ، عَنْ أُمِّ سَلَمَةَ، قَالَتْ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّكُمْ تَخْتَصِمُونَ إِلَىَّ وَإِنَّمَا أَنَا بَشَرٌ وَلَعَلَّ بَعْضَكُمْ أَنْ يَكُونَ أَلْحَنَ بِحُجَّتِهِ مِنْ بَعْضٍ فَإِنْ قَضَيْتُ لأَحَدٍ مِنْكُمْ بِشَيْءٍ مِنْ حَقِّ أَخِيهِ فَإِنَّمَا أَقْطَعُ لَهُ قِطْعَةً مِنَ النَّارِ فَلاَ يَأْخُذْ مِنْهُ شَيْئًا " . قَالَ وَفِي الْبَابِ عَنْ أَبِي هُرَيْرَةَ وَعَائِشَةَ . قَالَ أَبُو عِيسَى حَدِيثُ أُمِّ سَلَمَةَ حَدِيثٌ حَسَنٌ صَحِيحٌ .
