"The Messenger of Allah [SAW] said: 'If a judge passes judgment and strives to reach the right conclusion and gets it right, he will have two rewards; if he strives to reach the right conclusion but gets it wrong, he will still have one reward."

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا حَكَمَ الْحَاكِمُ فَاجْتَهَدَ فَأَصَابَ فَلَهُ أَجْرَانِ وَإِذَا اجْتَهَدَ فَأَخْطَأَ فَلَهُ أَجْرٌ

[Machine] I heard him say that my two opponents have taken their dispute to Amr ibn al-As and he ruled between them. The one who lost the case became angry with the judge, so he went to the Messenger of Allah ﷺ and informed him. The Messenger of Allah ﷺ said, "When the judge makes a decision and strives to do so, and he is correct, he will have ten rewards. But if he strives and makes a mistake, he will still have one or two rewards."

سَمِعْتُهُ يَقُولُ إِنَّ خَصْمَيْنِ اخْتَصَمَا إِلَى عَمْرِو بْنِ الْعَاصِي فَقَضَى بَيْنَهُمَا فَسَخِطَ الْمَقْضِيُّ عَلَيْهِ فَأَتَى رَسُولَ اللهِ ﷺ فَأَخْبَرَهُ فَقَالَ رَسُولُ اللهِ ﷺ إِذَا قَضَى الْقَاضِي فَاجْتَهَدَ فَأَصَابَ فَلَهُ عَشَرَةُ أُجُورٍ وَإِذَا اجْتَهَدَ فَأَخْطَأَ كَانَ لَهُ أَجْرٌ أَوْ أَجْرَانِ
