The word(s) "oppress" appears 10 time(s) in 10 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And fight with them until there is no persecution, and religion should be only for Allah, but if they desist, then there should be no hostility except against the oppressors.

(2) And what reason have you that you should not fight in the way of Allah and of the weak among the men and the women and the children, (of) those who say: Our Lord! cause us to go forth from this town, whose people are oppressors, and give us from Thee a guardian and give us from Thee a helper.

(3) And We made the children of Israel to pass through the sea, then Firon and his hosts followed them for oppression and tyranny; until when drowning overtook him, he said: I believe that there is no god but He in Whom the children of Israel believe and I am of those who submit.

(4) And those who fly for Allah's sake after they are oppressed, We will most certainly give them a good abode in the world, and the reward of the hereafter is certainly much greater, did they but know;

(5) Permission (to fight) is given to those upon whom war is made because they are oppressed, and most surely Allah is well able to assist them;

(6) That (shall be so); and he who retaliates with the like of that with which he has been afflicted and he has been oppressed, Allah will most certainly aid him; most surely Allah is Pardoning, Forgiving.

(7) Except those who believe and do good and remember Allah much, and defend themselves after they are oppressed; and they who act unjustly shall know to what final place of turning they shall turn back.

(8) And whoever defends himself after his being oppressed, these it is against whom there is no way (to blame).

(9) The way (to blame) is only against those who oppress men and revolt in the earth unjustly; these shall have a painful punishment.

(10) Therefore, as for the orphan, do not oppress (him).
