كتاب القضاء
Read the English translation first, with the original Arabic directly underneath.
Narrated Buraida (RA) Allah's Messenger (ﷺ) said:
"al-Qudat (judges) are of three types, two of whom will go to Hell and one to Paradise. The one who will go to Paradise is a man who knows what is right and gives judgement accordingly. However, a man who knows what is right, and does not give judgement accordingly and acts unjustly in his judgement, will be in the Hell-fire. Likewise, a man who does not know what is right and judges people with ignorance, will be in the Hell-fire." [Reported by al-Arba'a, and al-Hakim graded it Sahih (authentic)].
اَلْقُضَاةُ ثَلَاثَةٌ: اِثْنَانِ فِي اَلنَّارِ, وَوَاحِدٌ فِي اَلْجَنَّةِ. رَجُلٌ عَرَفَ اَلْحَقَّ, فَقَضَى بِهِ, فَهُوَ فِي اَلْجَنَّةِ. وَرَجُلٌ عَرَفَ اَلْحَقَّ, فَلَمْ يَقْضِ بِهِ, وَجَارَ فِي اَلْحُكْمِ, فَهُوَ فِي اَلنَّارِ. وَرَجُلٌ لَمْ يَعْرِفِ اَلْحَقَّ, فَقَضَى لِلنَّاسِ عَلَى جَهْلٍ, فَهُوَ فِي اَلنَّارِ
