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

(311) And he made it [i.e. La ilaha illallah (none has the right to be worshipped but Allah Alone)] a Word lasting among his offspring, (True Monotheism), that they may turn back (i.e. to repent to Allah or receive admonition).

(312) And whosoever turns away blindly from the remembrance of the Most Gracious (Allah) (i.e. this Qur'an and worship of Allah), We appoint for him Shaitan (Satan - devil) to be a Qarin (a companion) to him.

(313) It will profit you not this Day (O you who turn away from Allah's remembrance and His worship) as you did wrong, (and) that you will be sharers (you and your Qarin ) in the punishment.

(314) And ask (O Muhammad صلى الله عليه و سلم) those of Our Messengers whom We sent before you: "Did We ever appoint alihah (gods) to be worshipped besides the Most Gracious (Allah)?"

(315) And when the son of Maryam (Mary) is quoted as an example [i.e. 'Îsa (Jesus) is worshipped like their idols], behold, your people cry aloud (laugh out at the example).

(316) "Verily, Allah! He is my Lord (God) and your Lord (God). So worship Him (Alone). This is the (only) Straight Path (i.e. Allah's religion of true Islamic Monotheism)."

(317) (It will be said to the true believers of Islamic Monotheism): My worshippers! No fear shall be on you this Day, nor shall you grieve,

(318) Say (O Muhammad صلى الله عليه و سلم): "If the Most Gracious (Allah) had a son (or children as you pretend), then I am the first of Allah's worshippers [who deny and refute this claim of yours (and the first to believe in Allah Alone and testify that He has no children)]." [Tafsir At-Tabari].

(319) It is He (Allah) Who is the only Ilah (God to be worshipped) in the heaven and the only Ilah (God to be worshipped) on the earth. And He be the All-Wise, the All-Knower.

(320) And if you ask them who created them, they will surely say: "Allah." How then are they turned away (from the worship of Allah, Who created them)?
