The word(s) "worship" appears 429 time(s) in 354 verse(s) in Quran in Mohsin Khan translation.

(271) Verily We have sent down the Book to you (O Muhammad صلى الله عليه وسلم) in truth: So worship Allah (Alone) by doing religious deeds sincerely for Allah's sake only.

(272) Surely the religion (i.e. the worship and the obedience) is for Allah only. And those who take Auliya' (protectors, helpers, lords, gods) besides Him (say): "We worship them only that they may bring us near to Allah." Verily Allah will judge between them concerning that wherein they differ. Truly, Allah guides not him who is a liar, and a disbeliever.

(273) He created you (all) from a single person (Adam); then made from him his wife [Hawwa' (Eve)]. And He has sent down for you of cattle eight pairs (of the sheep, two, male and female; of the goats, two, male and female; of the oxen, two, male and female; and of the camels, two, male and female). He creates you in the wombs of your mothers: creation after creation in three veils of darkness. Such is Allah your Lord. His is the kingdom. La ilaha illa Huwa (none has the right to be worshipped but He). How then are you turned away?

(274) Say (O Muhammad صلى الله عليه وسلم): "O My slaves who believe (in the Oneness of Allah - Islamic Monotheism), be afraid of your Lord (Allah) and keep your duty to Him. Good is (the reward) for those who do good in this world, and Allah's earth is spacious (so if you cannot worship Allah at a place, then go to another)! Only those who are patient shall receive their reward in full, without reckoning. "

(275) Say (O Muhammad صلى الله عليه وسلم): "Verily I am commanded to worship Allah (Alone) by obeying Him and doing religious deeds sincerely for His sake only.

(276) Say (O Muhammad صلى الله عليه وسلم): "Allah Alone I worship by doing religious deeds sincerely for His sake only (and not to show off, and not to set up rivals with Him in worship.)"

(277) So worship what you like besides Him. Say (O Muhammad صلى الله عليه وسلم): "The losers are those who will lose themselves and their families on the Day of Resurrection. Verily, that will be a manifest loss!"

(278) Those who avoid At-Taghut (false deities) by not worshipping them and turn to Allah (in repentance), for them are glad tidings; so announce the good news to My slaves -

(279) Those who listen to the Word [good advice La ilaha illallah - (none has the right to be worshipped but Allah) and Islamic Monotheism] and follow the best thereof (i.e. worship Allah Alone, repent to Him and avoid Taghut) those are (the ones) whom Allah has guided and those are men of understanding.

(280) Allah puts forth a similitude: a (slave) man belonging to many partners (like those who worship others along with Allah) disputing with one another, and a (slave) man belonging entirely to one master (like those who worship Allah Alone). Are those two equal in comparison? All the praises and thanks be to Allah! But most of them know not.
