Allah Ta'ala says, "O you who believe! Stand firmly for justice, as witnesses to Allah, even as against yourselves, or your parents, or your kin, and whether it be (against) rich or poor: for Allah can best protect both. Follow not the lusts (of your hearts), lest ye swerve, and if you distort (justice) or decline to do justice, verily Allah is well- acquainted with all that you do" [An-Nisa, 4:135].
And the Messenger of Allah, Allah bless him and give him peace, who was the epitome of grace and good manners, even with his enemies, said, "Help your brother, whether he is an oppressor or he is an oppressed one. People asked, "O Messenger of Allah! It is all right to help him if he is oppressed, but how should we help him if he is an oppressor?" The Prophet said, "By preventing him from oppressing others" (Bukhari).
