hadith

You Shall Know The Truth And The Truth Shall Set You Free

Prophet Muhammad (peace be upon him) said, "Help your brother whether he is an oppressor or an oppressed person.

A companion asked: 'Messenger of Allah (it is true) I will help him if he is an oppressed person, but please tell me how I am to help him if he happens to be an oppressor.'

TheProphet (Pbuh) answered: check him from doing injustice. Because preventing him from committing aggression is a help to him."
