حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُعَلَّى بْنُ مَنْصُورٍ، عَنْ عَبْدِ اللَّهِ بْنِ جَعْفَرٍ، عَنْ عُثْمَانَ بْنِ مُحَمَّدٍ، عَنِ الْمَقْبُرِيِّ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ قَالَ ‏"‏ مَنْ جُعِلَ قَاضِيًا بَيْنَ النَّاسِ فَقَدْ ذُبِحَ بِغَيْرِ سِكِّينٍ ‏"‏ ‏.‏

It was narrated that 'Ali said

“The Messenger of Allah (ﷺ) sent me to Yemen. I said: 'O Messenger of Allah, you are sending me to judge between them while I am a young man, and I do not know how to judge.' He struck me on the chest with his hand and said: 'O Allah, guide his heart and make his tongue steadfast.' And after that I never doubted in passing judgment between two people.”
