The word(s) "justice" appears 42 time(s) in 37 verse(s) in Quran in Mohsin Khan translation.

(31) He [Musa (Moses)] said: "That (is settled) between me and you: whichever of the two terms I fulfil, there will be no injustice to me, and Allah is Surety over what we say."

(32) When they entered in upon Dawud (David), he was terrified of them. They said: "Fear not! (We are) two litigants, one of whom has wronged the other, therefore judge between us with truth, and treat us not with injustice, and guide us to the Right Way.

(33) O Dawud (David)! Verily! We have placed you as a successor on the earth; so judge you between men in truth (and justice) and follow not your desire - for it will mislead you from the Path of Allah. Verily, those who wander astray from the Path of Allah (shall) have a severe torment, because they forgot the Day of Reckoning.

(34) This Day shall every person be recompensed for what he earned. This Day no injustice (shall be done to anybody). Truly, Allah is Swift in reckoning.

(35) "Like the fate of the people of Nuh (Noah), and 'Ad, and Thamud and those who came after them. And Allah wills no injustice for (His) slaves.

(36) So unto this (religion of Islam alone and this Qur'an) then invite (people) (O Muhammad صلى الله عليه و سلم), and stand firm [on Islamic Monotheism by performing all that is ordained by Allah (good deeds), and by abstaining from all that is forbidden by Allah (sins and evil deeds)], as you are commanded, and follow not their desires but say: "I believe in whatsoever Allah has sent down of the Book [all the holy Books, - this Qur'an and the Books of the old from the Taurat (Torah), or the Injeel (Gospel) or the Pages of Ibrahim (Abraham)] and I am commanded to do justice among you. Allah is our Lord and your Lord. For us our deeds and for you your deeds. There is no dispute between us and you. Allah will assemble us (all), and to Him is the final return."

(37) Indeed We have sent Our Messengers with clear proofs, and revealed with them the Scripture and the Balance (justice) that mankind may keep up justice. And We brought forth iron wherein is mighty power (in matters of war ), as well as many benefits for mankind, that Allah may test who it is that will help Him (His religion) and His Messengers in the unseen. Verily, Allah is All-Strong, All-Mighty.
