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

(181) Or have they taken (for worship) alihah (gods) from the earth who raise the dead?

(182) Or have they taken for worship (other) alihah (gods) besides Him? Say: "Bring your proof." This (the Qur'an) is the Reminder for those with me and the Reminder for those before me. But most of them know not the Truth, so they are averse.

(183) And We did not send any Messenger before you (O Muhammad صلى الله عليه وسلم) but We revealed to him (saying): La ilaha illa Ana [none has the right to be worshipped but I (Allah)], so worship Me (Alone and none else)."

(184) Say (O Muhammad صلى الله عليه وسلم): "I warn you only by the revelation (from Allah and not by the opinion of the religious scholars and others). But the deaf (who follow the religious scholars and others blindly) will not hear the call, (even) when they are warned [i.e. one should follow only the Qur'an and the Sunnah (legal ways, orders, acts of worship, and the statements of Prophet Muhammad صلى الله عليه وسلم, as the companions of the Prophet صلى الله عليه وسلم did)] .

(185) They said: "We found our fathers worshipping them."

(186) [Ibrahim (Abraham)] said: "Do you then worship besides Allah, things that can neither profit you, nor harm you?

(187) "Fie upon you, and upon that which you worship besides Allah! Have you then no sense?"

(188) And We made them leaders, guiding (mankind) by Our Command, and We revealed to them the doing of good deeds, performing Salat (Iqamat-as-Salat), and the giving of Zakat and of Us (Alone) they were the worshippers.

(189) So We answered his call, and We removed the distress that was on him, and We restored his family to him (that he had lost) and the like thereof along with them as a mercy from Ourselves and a Reminder for all those who worship Us.

(190) And (remember) Dhun-Nun (Jonah), when he went off in anger, and imagined that We shall not punish him (i.e. the calamities which had befallen him)! But he cried through the darkness (saying): La ilaha illa Anta [none has the right to be worshipped but You (O, Allah)], Glorified (and Exalted) be You [above all that (evil) they associate with You]! Truly, I have been of the wrong-doers."
