Narrated Abu Bakrah (RA):

I heard Allah's Messenger (ﷺ) say, "No judge should give judgement between two people while he is angry." [Agreed upon].

وَعَنْ أَبِي بَكْرَةَ ‏- رضى الله عنه ‏- قَالَ: سَمِعْتُ رَسُولَ اَللَّهِ ‏- صلى الله عليه وسلم ‏-يَقُولُ: {

لَا يَحْكُمُ أَحَدٌ بَيْنَ اِثْنَيْنِ, وَهُوَ غَضْبَانُ

} مُتَّفَقٌ عَلَيْهِ [1]‏ .‏
