The word(s) "act" appears 129 time(s) in 119 verse(s) in Quran in Mohsin Khan translation.

(41) And the foremost to embrace Islam of the Muhajirun (those who migrated from Makkah to Al-Madinah) and the Ansar (the citizens of Al-Madinah who helped and gave aid to the Muhajirun ) and also those who followed them exactly (in Faith). Allah is well-pleased with them as they are well-pleased with Him. He has prepared for them Gardens under which rivers flow (Paradise), to dwell therein forever. That is the supreme success.

(42) And were Allah to hasten for mankind the evil (they invoke for themselves and for their children. while in a state of anger) as He hastens for them the good (they invoke) then they would have been ruined. So We leave those who expect not their meeting with Us, in their trespasses, wandering blindly in distraction. (Tafsir At-Tabari)

(43) There! Every person will know (exactly) what he had earned before and they will be brought back to Allah, their rightful Maula (Lord), and their invented false deities will vanish from them.

(44) Is it then that when it has actually befallen, you will believe in it? What! Now (you believe)? And you used (aforetime) to hasten it on!"

(45) No doubt! Verily, to Allah belongs whosoever is in the heavens and whosoever is in the earth. And those who worship and invoke others besides Allah, in fact they follow not (Allah's so-called) partners, they follow only a conjecture and they only invent lies.

(46) By no means will they escape (from Allah's Torment) on earth, nor have they protectors besides Allah! Their torment will be doubled! They could not bear to hear (the preachers of the truth) and they used not to see (the truth because of their severe aversion, in spite of the fact that they had the sense of hearing and sight).

(47) The chiefs who disbelieved among his people said: "We see you but a man like ourselves, nor do we see any follow you but the meanest among us and they (too) followed you without thinking. And we do not see in you any merit above us, in fact we think you are liars."

(48) "And O my people! act according to your ability and way, and I am acting (on my way). You will come to know who it is on whom descends the torment that will cover him with ignominy, and who is a liar! And watch you! Verily, I too am watching with you."

(49) And say to those who do not believe: "act according to your ability and way, We are acting (in our way).

(50) And she, in whose house he was, sought to seduce him (to do an evil act), and she closed the doors and said: "Come on, O you." He said: "I seek refuge in Allah (or Allah forbid)! Truly, he (your husband) is my master! He made my living in a great comfort! (So I will never betray him). Verily, the Zalimun (wrong and evil-doers) will never be successful."
