The word(s) "worship" appears 171 time(s) in 153 verse(s) in Quran in Abdullah Yusuf Ali translation.

(101) And he diverted her from the worship of others besides Allah: for she was (sprung) of a people that had no faith.

(102) Those against whom the charge will be proved, will say: "Our Lord! These are the ones whom we led astray: we led them astray, as we were astray ourselves: we free ourselves (from them) in Thy presence: it was not us they worshipped."

(103) We have enjoined on man kindness to parents: but if they (either of them) strive (to force) thee to join with Me (in worship) anything of which thou hast no knowledge, obey them not. Ye have (all) to return to me, and I will tell you (the truth) of all that ye did.

(104) "For ye do worship idols besides Allah, and ye invent falsehood. The things that ye worship besides Allah have no power to give you sustenance: then seek ye sustenance from Allah, serve Him, and be grateful to Him: to Him will be your return.

(105) And he said: "For you, ye have taken (for worship) idols besides Allah, out of mutual love and regard between yourselves in this life; but on the Day of Judgment ye shall disown each other and curse each other: and your abode will be the Fire, and ye shall have none to help."

(106) Now, if they embark on a boat, they call on Allah, making their devotion sincerely (and exclusively) to Him; but when He has delivered them safely to (dry) land, behold, they give a share (of their worship to others)!-

(107) When trouble touches men, they cry to their Lord, turning back to Him in repentance: but when He gives them a taste of Mercy as from Himself, behold, some of them pay part-worship to other god's besides their Lord,-

(108) Or have We sent down authority to them, which points out to them the things to which they pay part-worship?

(109) Say: "Travel through the earth and see what was the end of those before (you): Most of them worshipped others besides Allah."

(110) Behold, Luqman said to his son by way of instruction: "O my son! join not in worship (others) with Allah: for false worship is indeed the highest wrong-doing."
