The word(s) "oppression" appears 15 time(s) in 15 verse(s) in Quran in Mohsin Khan translation.

(11) Evil (sins and disobedience to Allah) has appeared on land and sea because of what the hands of men have earned (by oppression and evil deeds), that He (Allah) may make them taste a part of that which they have done, in order that they may return (by repenting to Allah, and begging His Pardon).

(12) His companion (Satan - devil)] will say: "Our Lord! I did not push him to transgression, (in disbelief, oppression, and evil deeds) but he was himself in error far astray."

(13) Then for him who transgressed all bounds, (in disbelief, oppression and evil deeds of disobedience to Allah).

(14) And none can deny it except every transgressor beyond bounds, (in disbelief, oppression and disobedience to Allah) the sinner!

(15) Therefore, treat not the orphan with oppression.
