The word(s) "doer" appears 188 time(s) in 184 verse(s) in Quran in Mohsin Khan translation.

(121) And (remember) when your Lord called Musa (Moses) (saying): "Go to the people who are Zalimun (polytheists and wrong-doers) -

(122) 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.).

(123) And when he attained his full strength, and was perfect (in manhood), We bestowed on him Hukm (Prophethood and right judgement of the affairs) and religious knowledge [of the religion of his forefathers i.e. Islamic Monotheism]. And thus do We reward the Muhsinun (i.e. good doers. See the footnote of V.9:120).

(124) So he escaped from there, looking about in a state of fear. He said: "My Lord! Save me from the people who are Zalimun (polytheists and wrong-doers)!"

(125) Then there came to him one of the two women, walking shyly. She said: "Verily, my father calls you that he may reward you for having watered (our flocks) for us." So when he came to him and narrated the story, he said: "Fear you not. You have escaped from the people who are Zalimun (polytheists, disbelievers, and wrong-doers)."

(126) Musa (Moses) said: "My Lord knows best him who came with guidance from Him, and whose will be the happy end in the Hereafter. Verily, the Zalimun (wrong-doers, polytheists and disbelievers in the Oneness of Allah) will not be successful."

(127) So We seized him and his hosts, and We threw them all into the sea (and drowned them). So behold (O Muhammad صلى الله عليه وسلم) what was the end of the Zalimun [wrong-doers, polytheists and those who disbelieved in the Oneness of their Lord (Allah), or rejected the advice of His Messenger Musa (Moses) عليه السلام].

(128) But if they answer you not (i.e. do not bring the Book nor believe in your doctrine of Islamic Monotheism), then know that they only follow their own lusts. And who is more astray than one who follows his own lusts, without guidance from Allah? Verily Allah guides not the people who are Zalimun (wrong-doers, disobedient to Allah, and polytheists).

(129) And never will your Lord destroy the towns (populations) until He sends to their mother town a Messenger reciting to them Our Verses. And never would We destroy the towns unless the people thereof are Zalimun (polytheists, wrong-doers, disbelievers in the Oneness of Allah, oppressors and tyrants).

(130) And indeed We sent Nuh (Noah) to his people, and he stayed among them a thousand years less fifty years [inviting them to believe in the Oneness of Allah (Monotheism), and discard the false gods and other deities]; and the Deluge overtook them while they were Zalimun (wrong-doers, polytheists, disbelievers).
