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

(51) And do not do mischief on the earth, after it has been set in order, and invoke Him with fear and hope. Surely, Allah's Mercy is (ever) near unto the good-doers.

(52) And the people of Musa (Moses) made in his absence, out of their ornaments, the image of a calf (for worship). It had a sound (as if it was mooing). Did they not see that it could neither speak to them nor guide them to the way? They took it (for worship) and they were Zalimun (wrong-doers).

(53) And when Musa (Moses) returned to his people, angry and grieved, he said: "What an evil thing is that which you have done (i.e. worshipping the calf) during my absence. Did you hasten and go ahead as regards the matter of your Lord (you left His worship)?" And he threw down the Tablets and seized his brother by (the hair of) his head and dragged him towards him. Harun (Aaron) said: "O son of my mother! Indeed the people judged me weak and were about to kill me, so make not the enemies rejoice over me, nor put me amongst the people who are Zalimun (wrong-doers)."

(54) And (remember) when it was said to them: "Dwell in this town (Jerusalem) and eat therefrom wherever you wish, and say, '(O Allah) forgive our sins'; and enter the gate prostrate (bowing with humility). We shall forgive you your wrong-doings. We shall increase (the reward) for the good-doers."

(55) In order that Allah may distinguish the wicked (disbelievers, polytheists and doers of evil deeds) from the good (believers of Islamic Monotheism and doers of righteous deeds), and put the wicked (disbelievers, polytheists and doers of evil deeds) one over another, heap them together and cast them into Hell. Those! it is they who are the losers.

(56) Similar to the behaviour of the people of Fir'aun (Pharaoh), and those before them. They belied the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of their Lord, so We destroyed them for their sins, and We drowned the people of Fir'aun (Pharaoh) for they were all Zalimun (polytheists and wrong-doers).

(57) Do you consider the providing of drinking water to the pilgrims and the maintenance of Al-Masjidal-Haram (at Makkah) as equal to the worth of those who believe in Allah and the Last Day, and strive hard and fight in the Cause of Allah? They are not equal before Allah. And Allah guides not those people who are the Zalimun (polytheists and wrong-doers).

(58) O you who believe! Take not as Auliya' (supporters and helpers) your fathers and your brothers if they prefer disbelief to Belief. And whoever of you does so, then he is one of the Zalimun (wrong-doers).

(59) Had they marched out with you, they would have added to you nothing except disorder, and they would have hurried about in your midst (spreading corruption) and sowing sedition among you - and there are some among you who would have listened to them. And Allah is the All-Knower of the Zalimun (polytheists and wrong-doers).

(60) There is no blame on those who are weak or ill or who find no resources to spend [in holy fighting (Jihad)], if they are sincere and true (in duty) to Allah and His Messenger. No ground (of complaint) can there be against the Muhsinun (good-doers - See the footnote of V.9:120). And Allah is Oft-Forgiving, Most Merciful.
