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

(141) Say (O Muhammad صلى الله عليه وسلم): "Tell me or inform me (what) do you think about your (so-called) partner-gods to whom you call upon besides Allah? Show me, what they have created of the earth. Or have they any share in the heavens? Or have We given them a Book, so that they act on clear proof therefrom? Nay, the Zalimun (polytheists and wrong-doers) promise one another nothing but delusions."

(142) Truly We have made it (as) a trail for the Zalimun (polytheists, disbelievers, wrong-doers).

(143) Verily, thus We reward the Muhsinun (good-doers - See V.2:112).

(144) You have fulfilled the dream!" Verily thus do We reward the Muhsinun (good-doers - See 2:112).

(145) Thus indeed do We reward the Muhsinun (good-doers - See V.2:112).

(146) Verily, thus do We reward the Muhsinun (good-doers - See V.2:112).

(147) Verily, thus do We reward the Muhsinun (good-doers, who perform good deeds totally for Allah's sake only - See V.2:112).

(148) Is he then, who will confront with his face the awful torment on the Day of Resurrection (as he who enters peacefully in Paradise)? And it will be said to the Zalimun (polytheists and wrong-doers): "Taste what you used to earn!"

(149) They shall have all that they will desire with their Lord. That is the reward of Muhsinun (good-doers - see the footnote of V.9:120).

(150) Or (lest) he should say when he sees the torment: "If only I had another chance (to return to the world), then I should indeed be among the Muhsinun (good-doers - See V.2:112)."
