Nahj al-Balāgha
Hadith 1459فَأَنْصِفُوا النَّاسَ مِنْ أَنْفُسِكُمْ، وَاصْبِرُوا لِحَوَائِجِهِمْ، فَإِنَّكُمْ خُزَّانُ الرَّعِيَّةِ، وَوُكَلَاءُ الْأُمَّةِ، وَسُفَرَاءُ الْأَئِمَّةِ،
Behave yourselves justly with the people and act with endurance with regard to their needs, because you are the treasurers of the people, representatives of the community and the ambassadors of the Imāms.
