Regarding the Judges judge when he is mistaken
Arabic hadith text
حَدَّثَنَا سُلَيْمَانُ بْنُ دَاوُدَ الْمَهْرِيُّ، أَخْبَرَنَا ابْنُ وَهْبٍ، عَنْ يُونُسَ بْنِ يَزِيدَ، عَنِ ابْنِ شِهَابٍ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، - رضى الله عنه - قَالَ وَهُوَ عَلَى الْمِنْبَرِ يَا أَيُّهَا النَّاسُإِنَّ الرَّأْىَ إِنَّمَا كَانَ مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم مُصِيبًا لأَنَّ اللَّهَ كَانَ يُرِيهِ وَإِنَّمَا هُوَ مِنَّا الظَّنُّ وَالتَّكَلُّفُ ‏.‏
Translation
Narrated Umar ibn al-Khattab

Umar ibn al-Khattab, may Allah be pleased with him, said while he was on the pulpit: O people, opinion was only ever correct from the Messenger of Allah, may Allah bless him and grant him peace, because Allah used to show him, whereas from us it is mere conjecture and artificial effort.
