Narrated Buraidah:

The Prophet ﷺ as saying: "Judges are of three types, one of who will go to Paradise and two to Hell. The one who will go to Paradise is a man who knows what is right and gives judgement accordingly; by a man who knows what is right and acts tyrannically in his judgement will go to Hell; and a man who gives judgement for people when he is ignorant will go to Hell."

Abu Dawud said: On this subject this is the soundest tradition, that is m the tradition of Ibn Buraidah: Judges are of three types.

حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ عُمَرَ بْنِ مَيْسَرَةَ، حَدَّثَنَا عَبْدُ الْعَزِيزِ، - يَعْنِي ابْنَ مُحَمَّدٍ - أَخْبَرَنِي يَزِيدُ بْنُ عَبْدِ اللَّهِ بْنِ الْهَادِ، عَنْ مُحَمَّدِ بْنِ إِبْرَاهِيمَ، عَنْ بُسْرِ بْنِ سَعِيدٍ، عَنْ أَبِي قَيْسٍ، مَوْلَى عَمْرِو بْنِ الْعَاصِ عَنْ عَمْرِو بْنِ الْعَاصِ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ
" إِذَا حَكَمَ الْحَاكِمُ فَاجْتَهَدَ فَأَصَابَ فَلَهُ أَجْرَانِ وَإِذَا حَكَمَ فَاجْتَهَدَ فَأَخْطَأَ فَلَهُ أَجْرٌ " . فَحَدَّثْتُ بِهِ أَبَا بَكْرِ بْنَ حَزْمٍ فَقَالَ هَكَذَا حَدَّثَنِي أَبُو سَلَمَةَ عَنْ أَبِي هُرَيْرَةَ .
