The word(s) "oppression" appears 3 time(s) in 3 verse(s) in Quran in Muhammad Pickthal translation.

(1) Say: My Lord forbiddeth only indecencies, such of them as are apparent and such as are within, and sin and wrongful oppression, and that ye associate with Allah that for which no warrant hath been revealed, and that ye tell concerning Allah that which ye know not.

(2) As for that Abode of the Hereafter We assign it unto those who seek not oppression in the earth, nor yet corruption. The sequel is for those who ward off (evil).

(3) And when we heard the guidance, we believed therein, and whoso believeth in his Lord, he feareth neither loss nor oppression.
