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

(101) They (Jews and Christians) took their rabbis and their monks to be their lords besides Allah (by obeying them in things which they made lawful or unlawful according to their own desires without being ordered by Allah), and (they also took as their Lord) Messiah, son of Maryam (Mary), while they (Jews and Christians) were commanded [in the Taurat (Torah) and the Injeel (Gospel)] to worship none but One Ilah (God - Allah) La ilaha illa Huwa (none has the right to be worshipped but He) . Praise and glory be to Him (far above is He) from having the partners they associate (with Him)."

(102) (The believers whose lives Allah has purchased are) those who turn to Allah in repentance (from polytheism and hypocrisy, etc.), who worship (Him), who praise (Him), who fast (or go out in Allah's Cause), who bow down (in prayer), who prostrate themselves (in prayer), who enjoin (on people) Al-Ma'ruf (i.e. Islamic Monotheism and all what Islam has ordained) and forbid (people) from Al-Munkar (i.e. disbelief, polytheism of all kinds and all that Islam has forbidden), and who observe the limits set by Allah (do all that Allah has ordained and abstain from all kinds of sins and evil deeds which Allah has forbidden). And give glad tidings to the believers.

(103) But if they turn away, say (O Muhammad صلى الله عليه وسلم): "Allah is sufficient for me. La ilaha illa Huwa (none has the right to be worshipped but He) in Him I put my trust and He is the Lord of the Mighty Throne."

(104) Surely, your Lord is Allah Who created the heavens and the earth in six Days and then rose over (Istawa ) the Throne (really in a manner that suits His Majesty), disposing the affair of all things. No intercessor (can plead with Him) except after His Leave. That is Allah, your Lord; so worship Him (Alone). Then, will you not remember?

(105) And they worship besides Allah things that harm them not, nor profit them, and they say: "These are our intercessors with Allah." Say: "Do you inform Allah of that which He knows not in the heavens and on the earth?" Glorified and Exalted is He above all that which they associate as partners (with Him)!

(106) And the Day whereon We shall gather them all together, then We shall say to those who did set partners in worship with Us: "Stop at your place! You and your partners (whom you had worshipped in the worldly life)." then We shall separate them, and their (Allah's so-called) partners shall say: "It was not us that you used to worship."

(107) "So sufficient is Allah as a witness between us and you that we indeed knew nothing of your worship of us."

(108) Say (O Muhammad صلى الله عليه وسلم): "Who provides for you from the sky and the earth? Or who owns hearing and sight? And who brings out the living from the dead and brings out the dead from the living? And who disposes the affairs?" They will say: "Allah." Say: "Will you not then be afraid of Allah's punishment (for setting up rivals in worship with Allah)?"

(109) And if every person who had wronged (by disbelieving in Allah and by worshipping others besides Allah) possessed all that is on the earth and sought to ransom himself therewith (it will not be accepted), and they would feel in their hearts regret when they see the torment, and they will be judged with justice, and no wrong will be done unto them.

(110) 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.
