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

(11) And fight them until there is no more Fitnah (disbelief and worshipping of others along with Allah) and (all and every kind of) worship is for Allah (Alone). But if they cease, let there be no transgression except against Az-Zalimun (the polytheists, and wrong-doers)

(12) And spend in the Cause of Allah (i.e. Jihad of all kinds) and do not throw yourselves into destruction (by not spending your wealth in the Cause of Allah), and do good. Truly, Allah loves Al-Muhsinun (the good-doers).

(13) The divorce is twice, after that, either you retain her on reasonable terms or release her with kindness. And it is not lawful for you (men) to take back (from your wives) any of your Mahr (bridal-money given by the husband to his wife at the time of marriage) which you have given them, except when both parties fear that they would be unable to keep the limits ordained by Allah (e.g. to deal with each other on a fair basis). Then if you fear that they would not be able to keep the limits ordained by Allah, then there is no sin on either of them if she gives back (the Mahr or a part of it) for her Al-Khul' (divorce) . These are the limits ordained by Allah, so do not transgress them. And whoever transgresses the limits ordained by Allah, then such are the Zalimun (wrong-doers).

(14) There is no sin on you, if you divorce women while yet you have not touched (had sexual relation with) them, nor appointed unto them their Mahr (bridal-money given by the husband to his wife at the time of marriage). But bestow on them (a suitable gift), the rich according to his means, and the poor according to his means, a gift of reasonable amount is a duty on the doers of good.

(15) Have you not thought about the group of the Children of Israel after (the time of) Musa (Moses)? When they said to a Prophet of theirs, "Appoint for us a king and we will fight in Allah's Way." He said, "Would you then refrain from fighting, if fighting was prescribed for you?" They said, "Why should we not fight in Allah's Way while we have been driven out of our homes and our children (families have been taken as captives)?" But when fighting was ordered for them, they turned away, all except a few of them. And Allah is All-Aware of the Zalimun (polytheists and wrong-doers).

(16) O you who believe! Spend of that with which We have provided for you, before a Day comes when there will be no bargaining, nor friendship, nor intercession. And it is the disbelievers who are the Zalimun (wrong-doers).

(17) Have you not looked at him who disputed with Ibrahim (Abraham) about his Lord (Allah), because Allah had given him the kingdom? When Ibrahim (Abraham) said (to him): "My Lord (Allah) is He Who gives life and causes death." He said, "I give life and cause death." Ibrahim (Abraham) said, "Verily! Allah brings the sun from the east; then bring it you from the west." So the disbeliever was utterly defeated. And Allah guides not the people, who are Zalimun (wrong-doers).

(18) And whatever you spend for spendings (e.g., in Sadaqah - charity for Allah's Cause) or whatever vow you make, be sure Allah knows it all. And for the Zalimun (wrong-doers) there are no helpers.

(19) And as for those who believe (in the Oneness of Allah) and do righteous good deeds, Allah will pay them their reward in full. And Allah does not like the Zalimun (polytheists and wrong-doers).

(20) How shall Allah guide a people who disbelieved after their belief and after they bore witness that the Messenger (Muhammad صلى الله عليه وسلم) is true and after clear proofs had come unto them? And Allah guides not the people who are Zalimun (polytheists and wrong-doers).
