            The most abominable (or divisive) thing is the injustice of judges
  أَفْظَعُ شَيْءٍ ظُلْمُ الْقُضَاةِ

            The worst of judges is one whose judgments are oppressive
  شَرُّ الْقُضَاةِ مَنْ جَارَتْ أَقْضِيَتُهُ [قَضِيَّتُهُ]

            One of the most excellent choices and best precautions [and supports] is for you to be just in your ruling (or judgment) and to carry it out among the special and the ordinary [people] equally
  مِنْ أَفْضَلِ الِاخْتِيَارِ وَأَحْسَنِ الِاسْتِظْهَارِ أَنْ تَعْدِلَ فِي الْحُكْمِ وَتُجْرِيَهُ فِي الْخَاصَّةِ وَالْعَامَّةِ عَلَى السَّوَاءِ
