´It was narrated from 'Amr bin 'As that he heard the Messenger of Allah (ﷺ) say:` “When the judge passes a judgement and does his best and gets it right, he will have two rewards, and if he passes a judgement and does his best and gets it wrong, he will have one reward.” (Sahih) Yazid (one of narrators) said : “So I Narrated it to Abu Bakr bin 'Amr bin Hazm. He said: 'This is how it was narrated to me by Abu Salamah from Abu Hurairah.'”

´Abu Hashim said:` “Were it not for the Hadith of Ibn Buraidah from his father, from the Prophet (ﷺ) who said: 'Judges are of three types, two of whom will be in Hell and one will be in Paradise. The man who knows the truth and rules in accordance with it, will be in Paradise. The man who passes judgment on the people in ignorance will be in Hell' - we would have said that if the judge does his best he will be in Paradise.”
