Al-Ma'idah 5:42

سَمَّٰعُونَ لِلْكَذِبِ أَكَّٰلُونَ لِلسُّحْتِ ۚ فَإِن جَآءُوكَ فَٱحْكُم بَيْنَهُمْ أَوْ أَعْرِضْ عَنْهُمْ ۖ وَإِن تُعْرِضْ عَنْهُمْ فَلَن يَضُرُّوكَ شَيْـًۭٔا ۖ وَإِنْ حَكَمْتَ فَٱحْكُم بَيْنَهُم بِٱلْقِسْطِ ۚ إِنَّ ٱللَّهَ يُحِبُّ ٱلْمُقْسِطِينَ

(They are fond of) listening to falsehood, of devouring anything forbidden. If they do come to thee, either judge between them, or decline to interfere. If thou decline, they cannot hurt thee in the least. If thou judge, judge in equity between them. For Allah loveth those who judge in equity.
