The word(s) "doing" appears 64 time(s) in 63 verse(s) in Quran in Mohsin Khan translation.

(51) So, call you (O Muhammad صلى الله عليه وسلم and the believers) upon (or invoke) Allah making (your) worship pure for Him (Alone) (by worshipping none but Him and by doing religious deeds sincerely for Allah's sake only and not to show off and not to set up rivals with Him in worship), however much the disbelievers (in the Oneness of Allah) may hate (it).

(52) He is the Ever Living, La ilaha illa Huwa (none has the right to be worshipped but He); so invoke Him making your worship pure for Him Alone (by worshipping Him Alone, and none else, and by doing righteous deeds sincerely for Allah's sake only, and not to show off, and not setting up rivals with Him in worship). All the praises and thanks be to Allah, the Lord of the 'Alamin (mankind, jinn and all that exists).

(53) And you have not been hiding yourselves (in the world), lest your ears, and your eyes, and your skins should testify against you; but you thought that Allah knew not much of what you were doing.

(54) And We have assigned for them (devils) intimate companions (in this world), who have made fair-seeming to them, what was before them (evil deeds which they were doing in the present worldly life and disbelief in the Reckoning and the Resurrection) and what was behind them (denial of the matters in the coming life of the Hereafter as regards punishment or reward). And the Word (i.e. the torment) is justified against them as it was justified against those who were among the previous generations of jinn and men that had passed away before them. Indeed they (all) were the losers.

(55) And if an evil whisper from Shaitan (Satan) tries to turn you away (O Muhammad صلى الله عليه وسلم) (from doing good), then seek refuge in Allah. Verily, He is the All-Hearer, the All-Knower.

(56) Marked by your Lord for the Musrifun (polytheists, criminals, sinners - those who trespass Allah's set limits in evil-doings by committing great sins).

(57) Have you not seen those who were forbidden to hold secret counsels, and afterwards returned to that which they had been forbidden, and conspired together for sin and wrong doing and disobedience to the Messenger (Muhammad صلى الله عليه وسلم). And when they come to you, they greet you with a greeting wherewith Allah greets you not, and say within themselves: "Why should Allah punish us not for what we say?" Hell will be sufficient for them; they will burn therein. And worst indeed is that destination!

(58) O you who believe! When you hold secret counsel, do it not for sin and wrong-doing, and disobedience towards the Messenger (Muhammad صلى الله عليه وسلم), but do it for Al-Birr (righteousness) and Taqwa (virtues and piety); and fear Allah unto Whom you shall be gathered.

(59) Therefore be patient (O Muhammad صلى الله عليه وسلم) with constancy to the Command of your Lord (Allah, by doing your duty to Him and by conveying His Message to mankind), and obey neither a sinner nor a disbeliever among them.

(60) And they witnessed what they were doing against the believers (i.e. burning them).
