The word(s) "act" appears 82 time(s) in 70 verse(s) in Quran in Muhammad Pickthal translation.

(11) O ye who believe! When ye rise up for prayer, wash you faces, and your hands up to the elbows, and lightly rub your heads and (wash) your feet up to the ankles. And if ye are unclean, purify yourselves. And if ye are sick or on a journey, or one of you cometh from the closet, or ye have had contact with women, and ye find not water, then go to clean, high ground and rub your faces and your hands with some of it. Allah would not place a burden on you, but He would purify you and would perfect His grace upon you, that ye may give thanks.

(12) Say: The evil and the good are not alike even though the plenty of the evil attract thee. So be mindful of your duty to Allah, O men of understanding, that ye may succeed.

(13) Had we sent down unto thee (Muhammad) (actual) writing upon parchment, so that they could feel it with their hands, those who disbelieve would have said: This is naught else than mere magic.

(14) How should I fear that which ye set up beside Him, when ye fear not to set up beside Allah that for which He hath revealed unto you no warrant? Which of the two factions hath more right to safety? (Answer me that) if ye have knowledge.

(15) Await they aught save the fulfilment thereof? On the day when the fulfilment thereof cometh, those who were before forgetful thereof will say: The messengers of our Lord did bring the Truth! Have we any intercessors, that they may intercede for us? Or can we be returned (to life on earth), that we may act otherwise than we used to act? They have lost their souls, and that which they devised hath failed them.

(16) Have they not considered the dominion of the heavens and the earth, and what things Allah hath created, and that it may be that their own term draweth nigh? In what fact after this will they believe?

(17) How (can there be any treaty for the others) when, if they have the upper hand of you, they regard not pact nor honour in respect of you? They satisfy you with their mouths the while their hearts refuse. And most of them are wrongdoers.

(18) And they observe toward a believer neither pact nor honour. These are they who are transgressors.

(19) And (there are) others who have acknowledged their faults. They mixed a righteous action with another that was bad. It may be that Allah will relent toward them. Lo! Allah is Forgiving, Merciful.

(20) And say (unto them): act! Allah will behold your actions, and (so will) His messenger and the believers, and ye will be brought back to the Knower of the Invisible and the Visible, and He will tell you what ye used to do.
