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

(161) And We have put coverings over their hearts lest they should understand it (the Qur'an), and in their ears deafness. And when you make mention of your Lord Alone [La ilaha illallah (none has the right to be worshipped but Allah) Islamic Monotheism (توحيد الله)] in the Qur'an, they turn on their backs, fleeing in extreme dislike.

(162) "These our people have taken for worship alihah (gods) other than Him (Allah). Why do they not bring for them a clear authority? And who does more wrong than he who invents a lie against Allah.

(163) (The young men said to one another): "And when you withdraw from them, and that which they worship, except Allah, then seek refuge in the Cave; your Lord will open a way for you from His Mercy and will make easy for you your affair (i.e. will give you what you will need of provision, dwelling)."

(164) And thus We made their case known (to the people), that they might know that the Promise of Allah is true, and that there can be no doubt about the Hour. (Remember) when they (the people of the city) disputed among themselves about their case, they said: "Construct a building over them; their Lord knows best about them;" (then) those who won their point said (most probably the disbelievers): "We verily shall build a place of worship over them."

(165) There (on the Day of Resurrection), Al-Walayah (protection, power, authority and kingdom) will be for Allah (Alone), the True God. He (Allah) is the Best for reward and the Best for the final end. (La ilaha illallah- none has the right to be worshipped but Allah).

(166) Say (O Muhammad صلى الله عليه وسلم): "I am only a man like you. It has been revealed to me that your Ilah (God) is One Ilah (God - i.e. Allah). So whoever hopes for the Meeting with his Lord, let him work righteousness and associate none as a partner in the worship of his Lord."

(167) ['Îsa (Jesus) said]: "And verily Allah is my Lord and your Lord. So worship Him (Alone). That is the Straight Path. (Allah's religion of Islamic Monotheism which He did ordain for all of His Prophets)." [Tafsir At-Tabari]

(168) When he said to his father: "O my father! Why do you worship that which hears not, sees not and cannot avail you in anything?

(169) "O my father! worship not Shaitan (Satan). Verily Shaitan (Satan) has been a rebel against the Most Gracious (Allah).

(170) So when he had turned away from them and from those whom they worshipped besides Allah, We gave him Ishaq (Isaac) and Ya'qub (Jacob), and each one of them We made a Prophet.
