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

(71) And As-Saihah (torment - awful cry) overtook the wrong-doers, so they lay (dead), prostrate in their homes,

(72) Marked from your Lord; and they are not ever far from the Zalimun (polytheists, evil-doers).

(73) And when Our Commandment came, We saved Shu'aib and those who believed with him by a Mercy from Us. And As-Saihah (torment-awful cry) seized the wrong-doers, and they lay (dead), prostrate in their homes.

(74) They will dwell therein for all the time that the heavens and the earth endure, except as your Lord wills. Verily, your Lord is the doer of whatsoever He intends (or wills).

(75) And be patient; verily, Allah wastes not the reward of the good-doers.

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

(77) And when he [Yusuf (Joseph)] attained his full manhood, We gave him wisdom and knowledge (the Prophethood); thus We reward the Muhsinun (doers of good - see the footnote of V.9:120).

(78) And she, in whose house he was, sought to seduce him (to do an evil act), and she closed the doors and said: "Come on, O you." He said: "I seek refuge in Allah (or Allah forbid)! Truly, he (your husband) is my master! He made my living in a great comfort! (So I will never betray him). Verily, the Zalimun (wrong and evil-doers) will never be successful."

(79) And there entered with him two young men in the prison. One of them said: "Verily, I saw myself (in a dream) pressing wine." The other said: "Verily, I saw myself (in a dream) carrying bread on my head and birds were eating thereof." (They said): "Inform us of the interpretation of this. Verily, we think you are one of the Muhsinun (doers of good)."

(80) Thus did We give full authority to Yusuf (Joseph) in the land, to take possession therein, when or where he likes. We bestow of Our Mercy on whom We will, and We make not to be lost the reward of Al-Muhsinun (the good doers - See V.2:112).
