The word(s) "action" appears 7 time(s) in 6 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And He it is Who created the heavens and the earth in six periods-- and His dominion (extends) on the water-- that He might manifest to you, which of you is best in action, and if you say, surely you shall be raised up after death, those who disbelieve would certainly say: This is nothing but clear magic.

(2) They said: The requital of this is that the person in whose bag it is found shall himself be (held for) the satisfaction thereof; thus do we punish the wrongdoers.

(3) The parable of those who disbelieve in their Lord: their actions are like ashes on which the wind blows hard on a stormy day; they shall not have power over any thing out of what they have earned; this is the great error.

(4) And We have made every man's actions to cling to his neck, and We will bring forth to him on the resurrection day a book which he will find wide open:

(5) O people! guard against (the punishment of) your Lord and dread the day when a father shall not make any satisfaction for his son, nor shall the child be the maker of any satisfaction for his father; surely the promise of Allah is true, therefore let not this world's life deceive you, nor let the archdeceiver deceive you in respect of Allah.

(6) And whoever is patient and forgiving, these most surely are actions due to courage.
