BUKHARI 2680: from Um Salamah —
Once Messenger of Allah ﷺ said, "You people present your cases to me and some of you may be more eloquent and persuasive in presenting their argument. So, if I give some one's right to another (wrongly) because of the latter's (tricky) presentation of the case, I am really giving him a piece of fire; so he should not take it."

البخاري ٢٦٨٠: عن ام سلمه —
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّكُمْ تَخْتَصِمُونَ إِلَىَّ وَلَعَلَّ بَعْضَكُمْ أَلْحَنُ بِحُجَّتِهِ مِنْ بَعْضٍ فَمَنْ قَضَيْتُ لَهُ بِحَقِّ أَخِيهِ شَيْئًا بِقَوْلِهِ فَإِنَّمَا أَقْطَعُ لَهُ قِطْعَةً مِنَ النَّارِ فَلاَ يَأْخُذْهَا
