The Prophet Muhammad (peace be upon him) said: "Help your brother, whether he is an oppressor or he is oppressed." The Prophet was asked: "It is right to help him if he is oppressed, but how should we help him if he is an oppressor?" He replied: "By preventing him from oppressing others." – [al-Bukhari]

And We reveal of the Qur'an that which is a healing and a mercy to the believers. And it causes nothing but loss to the unjust. [al-Isra’, 17:82]
