Translated by Sayyid Ali Reza

وَقَالَ (عليه ‏السلام):

Amir al-mu'minin, peace be upon him, said:

لِلظَّالِمِ مِنَ الرِّجَالِ ثَلاَثُ عَلاَمَاتٍ:

The oppressor among the people has three signs:

يَظْلِمُ مَنْ فَوْقَهُ بِالْمَعْصِيَةِ،

he oppresses his superior by disobeying him,

مَنْ دُونَهُ بِالْغَلَبَةِ

and his junior by imposing his authority

و يُظَاهِرُالْقَوْمَ الظَّلَمَةَ .

and he supports other oppressors.
