Comparing justice and generosity's merits
Nahj al-Balāgha|Volume 1|Book 3|Chapter 437
الْعَدْلُ يَضَعُ الْأُمُورَ مَوَاضِعَهَا، والْجُودُ يُخْرِجُهَا عَنْ جِهَتِهَا، وَالْعَدْلُ سَائِسٌ عَامٌّ، وَالْجُودُ عَارضٌ خَاصٌّ، فَالْعَدْلُ أَشْرَفُهُمَا وَأَفْضَلُهُمَا.
Justice puts things in their places while generosity takes them out from their directions; justice is the general caretaker while generosity is a particular benefit. Consequently, justice is superior and more distinguished of the two.
