Hadith on Oppression: Support oppressors by stopping them

Anas ibn Malik reported: The Messenger of Allah, peace and blessings be upon him, said, “Help your brother, whether he is an oppressor or is oppressed.” It was said, “O Messenger of Allah, we help the oppressed, but how do we help an oppressor?” The Prophet said, “By seizing his hand.

In another narration, the Prophet said, “By restraining him or preventing him from committing injustice, for that is how you support him.”
