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

(1) You (Alone) we worship, and You (Alone) we ask for help (for each and everything).

(2) O mankind! worship your Lord (Allah), Who created you and those who were before you so that you may become Al-Muttaqun (the pious - See V.2:2).

(3) Who has made the earth a resting place for you, and the sky as a canopy, and sent down water (rain) from the sky and brought forth therewith fruits as a provision for you. Then do not set up rivals unto Allah (in worship) while you know (that He Alone has the right to be worshipped).

(4) And (remember) when We appointed for Musa (Moses) forty nights, and (in his absence) you took the calf (for worship), and you were Zalimun (polytheists and wrong-doers).

(5) And (remember) when Musa (Moses) said to his people: "O my people! Verily, you have wronged yourselves by worshipping the calf. So turn in repentance to your Creator and kill yourselves (the innocent kill the wrongdoers among you), that will be better for you with your Creator." Then He accepted your repentance. Truly, He is the One Who accepts repentance, the Most Merciful.

(6) And (remember) when We took a covenant from the Children of Israel, (saying): worship none but Allah (Alone) and be dutiful and good to parents, and to kindred, and to orphans and Al-Masakin (the poor), and speak good to people [i.e. enjoin righteousness and forbid evil, and say the truth about Muhammad صلى الله عليه وسلم], and perform As-Salat (Iqamat-as-Salat), and give Zakat. Then you slid back, except a few of you, while you are backsliders. (Tafsir Al-Qurtubi).

(7) And indeed Musa (Moses) came to you with clear proofs, yet you worshipped the calf after he left, and you were Zalimun (polytheists and wrongdoers).

(8) And (remember) when We took your covenant and We raised above you the Mount (saying), "Hold firmly to what We have given you and hear (Our Word)." They said, "We have heard and disobeyed." And their hearts absorbed (the worship of) the calf because of their disbelief. Say: "Worst indeed is that which your faith enjoins on you if you are believers."

(9) And they (Jews, Christians and pagans) say: Allah has begotten a son (children or offspring) . Glory be to Him (Exalted be He above all that they associate with Him). Nay, to Him belongs all that is in the heavens and on earth, and all surrender with obedience (in worship) to Him.

(10) Or were you witnesses when death approached Ya'qub (Jacob)? When he said unto his sons, "What will you worship after me?" They said, "We shall worship your Ilah (God - Allah), the Ilah (God) of your fathers, Ibrahim (Abraham), Isma'il (Ishmael), Ishaq (Isaac), One Ilah (God), and to Him we submit (in Islam)."
