Yes. In a hadith qudsi Allah says that He has made oppression unlawful for Himself and unlawful among people, so do not oppress one another. The Quran warns that Allah is not unaware of what the wrongdoers do (14:42).
il n'y a de voie [de recours] que contre ceux qui lèsent les gens et commettent des abus, contrairement au droit, sur la terre: ceux-là auront un châtiment douloureux.
