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

(201) O you who have believed! Bow down, and prostrate yourselves, and worship your Lord and do good that you may be successful.

(202) And indeed We sent Nuh (Noah) to his people, and he said: "O my people! worship Allah! You have no other Ilah (God) but Him (Islamic Monotheism). Will you not then be afraid (of Him i.e. of His punishment because of worshipping others besides Him)?"

(203) And when you have embarked on the ship, you and whoever is with you, then say: "All the praises and thanks be to Allah, Who has saved us from the people who are Zalimun (i.e. oppressors, wrong-doers, polytheists, those who join others in worship with Allah).

(204) And We sent to them a Messenger from among themselves (saying): "worship Allah! You have no other Ilah (God) but Him. Will you not then be afraid (of Him i.e. of His punishment because of worshipping others besides Him)?"

(205) And those who join not anyone (in worship) as partners with their Lord;

(206) Or say they: There is madness in him? Nay, but he brought them the truth [i.e. Tauhid: worshipping Allah Alone in all aspects, the Qur'an and the religion of Islam], but most of them (the disbelievers) are averse to the truth.

(207) So Exalted be Allah, the True King: La ilaha illa Huwa (none has the right to be worshipped but He), the Lord of the Supreme Throne!

(208) And whoever invokes (or worships), besides Allah, any other ilah (god), of whom he has no proof; then his reckoning is only with his Lord. Surely! Al-Kafirun (the disbelievers in Allah and in the Oneness of Allah, polytheists, pagans, idolaters) will not be successful.

(209) Allah has promised those among you who believe and do righteous good deeds, that He will certainly grant them succession to (the present rulers) in the land, as He granted it to those before them, and that He will grant them the authority to practise their religion which He has chosen for them (i.e. Islam). And He will surely give them in exchange a safe security after their fear (provided) they (believers) worship Me and do not associate anything (in worship) with Me. But whoever disbelieves after this, they are the Fasiqun (rebellious, disobedient to Allah).

(210) Make not the calling of the Messenger (Muhammad صلى الله عليه وسلم) among you as your calling one of another. Allah knows those of you who slip away under shelter (of some excuse without taking the permission to leave, from the Messenger (صلى الله عليه وسلم). And let those who oppose the Messenger's (Muhammad صلى الله عليه وسلم) commandment (i.e. his Sunnah - legal ways, orders, acts of worship, statements) (among the sects) beware, lest some Fitnah (disbelief, trials, afflictions, earthquakes, killing, overpowered by a tyrant) should befall them or a painful torment be inflicted on them.
