The word(s) "injustice" appears 19 time(s) in 19 verse(s) in Quran in Muhammad Habib Shakir translation.

(11) And We did not do them injustice, but they were unjust to themselves, so their gods whom they called upon besides Allah did not avail them aught when the decree of your Lord came to pass; and they added but to their ruin.

(12) And they ask you to hasten on the evil before the good, and indeed there have been exemplary punishments before them; and most surely your Lord is the Lord of forgiveness to people, notwithstanding their injustice; and most surely your Lord is severe in requiting (evil).

(13) And for those who were Jews We prohibited what We have related to you already, and We did them no injustice, but they were unjust to themselves.

(14) And nothing could have hindered Us that We should send signs except that the ancients rejected them; and We gave to Samood the she-camel-- a manifest sign-- but on her account they did injustice, and We do not send signs but to make (men) fear.

(15) And whoever does good works and he is a believer, he shall have no fear of injustice nor of the withholding of his due.

(16) And those who disbelieve say: This is nothing but a lie which he has forged, and other people have helped him at it; so indeed they have done injustice and (uttered) a falsehood.

(17) This day every soul shall be rewarded for what it has earned; no injustice (shall be done) this day; surely Allah is quick in reckoning.

(18) The like of what befell the people of Nuh and Ad and Samood and those after them, and Allah does not desire injustice for (His) servants;

(19) O Prophet! when you divorce women, divorce them for~ their prescribed time, and calculate the number of the days prescribed, and be careful of (your duty to) Allah, your Lord. Do not drive them out of their houses, nor should they themselves go forth, unless they commit an open indecency; and these are the limits of Allah, and whoever goes beyond the limits of Allah, he indeed does injustice to his own soul. You do not know that Allah may after that bring about reunion.
