وَعَنْ عَائِشَةَ رَضِيَ اَللَّهُ عَنْهَا
قَالَتْ: سَمِعْتُ رَسُولَ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «يُدْعَى بِالْقَاضِي اَلْعَادِلِ يَوْمَ اَلْقِيَامَةِ، فَيَلْقَى مِنْ شِدَّةِ اَلْحِسَابِ مَا يَتَمَنَّى أَنَّهُ لَمْ يَقْضِ بَيْنَ اِثْنَيْنِ فِي عُمْرِهِ»
I heard the Messenger of Allah (sallallahu alayhi wa sallam) saying, “the just Qadi (judge) will be called (forth) on the Day of Resurrection and he will wish he had never given judgement even between two men throughout his life, due to the severity of the account he will face.” [Reported by Ibn Hibban. al-Baihaqi reported it with the wording: “…concerning a single tamrah (date fruit).”
