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

(91) Those who join not (in worship) partners with their Lord;

(92) Allah has promised, to those among you who believe and work righteous deeds, that He will, of a surety, grant them in the land, inheritance (of power), as He granted it to those before them; that He will establish in authority their religion - the one which He has chosen for them; and that He will change (their state), after the fear in which they (lived), to one of security and peace: 'They will worship Me (alone) and not associate aught with Me. 'If any do reject Faith after this, they are rebellious and wicked.

(93) The day He will gather them together as well as those whom they worship besides Allah, He will ask: "Was it ye who let these My servants astray, or did they stray from the Path themselves?"

(94) Yet do they worship, besides Allah, things that can neither profit them nor harm them: and the Misbeliever is a helper (of Evil), against his own Lord!

(95) Behold, he said to his father and his people: "What worship ye?"

(96) They said: "We worship idols, and we remain constantly in attendance on them."

(97) He said: "Do ye then see whom ye have been worshipping,-

(98) "And it shall be said to them: 'Where are the (gods) ye worshipped-

(99) "I found her and her people worshipping the sun besides Allah: Satan has made their deeds seem pleasing in their eyes, and has kept them away from the Path,- so they receive no guidance,-

(100) "(Kept them away from the Path), that they should not worship Allah, Who brings to light what is hidden in the heavens and the earth, and knows what ye hide and what ye reveal.
