The word(s) "good-doer" appears 30 time(s) in 30 verse(s) in Quran in Mohsin Khan translation.

(11) 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."

(12) 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.

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

(14) They said: "O ruler of the land! Verily, he has an old father (who will grieve for him); so take one of us in his place. Indeed we think that you are one of the Muhsinun (good-doers - see the footnote of V.9:120)."

(15) They said: "Are you indeed Yusuf (Joseph)?" He said: "I am Yusuf (Joseph), and this is my brother (Benjamin). Allah has indeed been gracious to us. Verily, he who fears Allah with obedience to Him (by abstaining from sins and evil deeds, and by performing righteous good deeds), and is patient, then surely, Allah makes not the reward of the Muhsinun (good-doers - see V.2:112) to be lost."

(16) Truly, Allah is with those who fear Him (keep their duty unto Him), and those who are Muhsinun (good-doers. See the footenote of V.9:120).

(17) A guide and a mercy for the Muhsinun (good-doers).

(18) And whosoever submits his face (himself) to Allah, while he is a Muhsin (good-doer i.e. performs good deeds totally for Allah's sake without any show off or to gain praise or fame and does them in accordance with the Sunnah of Allah's Messenger Muhammad صلى الله عليه وسلم), then he has grasped the most trustworthy handhold [La ilaha illallah (none has the right to be worshipped but Allah)]. And to Allah return all matters for decision.

(19) "But if you desire Allah and His Messenger, and the home of the Hereafter, then verily, Allah has prepared for Al-Muhsinat (good-doers) amongst you an enormous reward."

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