The word(s) "unjust" appears 39 time(s) in 38 verse(s) in Quran in Mohsin Khan translation.

(11) This is because of that (evil) which your hands have sent before you. And certainly, Allah is never unjust to (His) slaves.

(12) Verily, those who unjustly eat up the property of orphans, they eat up only fire into their bellies, and they will be burnt in the blazing Fire!

(13) O you who believe! Eat not up your property among yourselves unjustly except it be a trade amongst you, by mutual consent. And do not kill yourselves (nor kill one another). Surely, Allah is Most Merciful to you.

(14) We sent no Messenger, but to be obeyed by Allah's Leave. If they (hypocrites), when they had been unjust to themselves, had come to you (Muhammad صلى الله عليه وسلم) and begged Allah's Forgiveness, and the Messenger had begged forgiveness for them: indeed, they would have found Allah All-Forgiving (One Who forgives and accepts repentance), Most Merciful.

(15) Have you not seen those who were told to hold back their hands (from fighting) and perform As-Salat (Iqamat-as-Salat), and give Zakat but when the fighting was ordained for them, behold! a section of them fear men as they fear Allah or even more. They say: "Our Lord! Why have you ordained for us fighting? Would that You had granted us respite for a short period?" Say: "Short is the enjoyment of this world. The Hereafter is (far) better for him who fears Allah, and you shall not be dealt with unjustly even equal to a scalish thread in the long slit of a date-stone.

(16) Because of their breaking the covenant, and of their rejecting the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, and of their killing the Prophets unjustly, and of their saying: "Our hearts are wrapped (with coverings, i.e. we do not understand what the Messengers say)" - nay, Allah has set a seal upon their hearts because of their disbelief, so they believe not but a little.

(17) Because of that We ordained for the Children of Israel that if anyone killed a person not in retaliation of murder, or (and) to spread mischief in the land - it would be as if he killed all mankind, and if anyone saved a life, it would be as if he saved the life of all mankind. And indeed, there came to them Our Messengers with clear proofs, evidence, and signs, even then after that many of them continued to exceed the limits (e.g. by doing oppression unjustly and exceeding beyond the limits set by Allah by committing the major sins) in the land!

(18) O you who believe! Take not the Jews and the Christians as Auliya' (friends, protectors, helpers), they are but Auliya' of each other. And if any amongst you takes them (as Auliya'), then surely he is one of them. Verily, Allah guides not those people who are the Zalimun (polytheists and wrong-doers and unjust).

(19) And turn not away those who invoke their Lord, morning and afternoon seeking His Face. You are accountable for them in nothing, and they are accountable for you in nothing, that you may turn them away, and thus become of the Zalimun (unjust).

(20) And who can be more unjust than he who invents a lie against Allah, or says: "A revelation has come to me" whereas no revelation has come to him in anything ; and who says, "I will reveal the like of what Allah has revealed." And if you could but see when the Zalimun (polytheists and wrong-doers) are in the agonies of death, while the angels are stretching forth their hands (saying): "Deliver your souls! This day you shall be recompensed with the torment of degradation because of what you used to utter against Allah other than the truth. And you used to reject His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) with disrespect! "
