The word(s) "wrongfully" appears 9 time(s) in 9 verse(s) in Quran in Mohsin Khan translation.

(1) And (remember) when you said, "O Musa (Moses)! We cannot endure one kind of food. So invoke your Lord for us to bring forth for us of what the earth grows, its herbs, its cucumbers, its Fum (wheat or garlic), its lentils and its onions." He said, "Would you exchange that which is better for that which is lower? Go you down to any town and you shall find what you want!" And they were covered with humiliation and misery, and they drew on themselves the Wrath of Allah. That was because they used to disbelieve the Ayat (proofs, evidence, verses, lessons, signs, revelations etc.) of Allah and killed the Prophets wrongfully. That was because they disobeyed and used to transgress the bounds (in their disobedience to Allah, i.e. commit crimes and sins).

(2) But if you intend to replace a wife by another and you have given one of them a Qintar (of gold i.e. a great amount as Mahr) take not the least bit of it back; would you take it wrongfully without a right and (with) a manifest sin?

(3) And their taking of Riba (usury) though they were forbidden from taking it and their devouring of men's substance wrongfully (bribery). And We have prepared for the disbelievers among them a painful torment.

(4) And insult not those whom they (disbelievers) worship besides Allah, lest they insult Allah wrongfully without knowledge. Thus We have made fair-seeming to each people its own doings; then to their Lord is their return and He shall then inform them of all that they used to do.

(5) Then after them We sent Musa (Moses) with Our Signs to Fir'aun (Pharaoh) and his chiefs, but they wrongfully rejected them. So see how was the end of the Mufsidun (mischief-makers, corrupters).

(6) But when He delivers them, behold! they rebel (disobey Allah) in the earth wrongfully. O mankind! Your rebellion (disobedience to Allah) is only against your ownselves, - a brief enjoyment of this worldly life, then (in the end) unto Us is your return, and We shall inform you of that which you used to do.

(7) And your Lord would never destroy the towns wrongfully, while their people were right-doers.

(8) And do not kill anyone whose killing Allah has forbidden, except for a just cause. And whoever is killed wrongfully (Mazluman intentionally with hostility and oppression and not by mistake), We have given his heir the authority [to demand Qisas, - Law of Equality in punishment - or to forgive, or to take Diyah (blood money)]. But let him not exceed limits in the matter of taking life (i.e he should not kill except the killer). Verily, he is helped (by the Islamic law).

(9) And they belied them (those Ayat) wrongfully and arrogantly, though their ownselves were convinced thereof [i.e. those (Ayat ) are from Allah, and Musa (Moses) is the Messenger of Allah in truth, but they disliked to obey Musa (Moses), and hated to believe in his Message of Monotheism]. So see what was the end of the Mufsidun (disbelievers, disobedient to Allah, evil-doers and liars.).
