Qatadah on Justice: Fulfill the measure as you would for yourself

Al-Tabari reported: Qatadah, may Allah have mercy on him, said, “O son of Adam, be just as you would love justice for yourself, and fulfill the measure as you would love for it to be fulfilled for yourself. Verily, in justice is the well-being of people.”

عن الطبري قال قَتَادَةَ رحمه الله اعْدِلْ يَا ابْنَ آدَمَ كَمَا تُحِبُّ أَنْ يُعْدَلَ عَلَيْكَ وَأَوْفِ كَمَا تُحِبُّ أَنْ يُوَفَّى لَكَ فَإِنَّ بِالْعَدْلِ صَلَاحَ النَّاسِ
