The word(s) "serve" appears 75 time(s) in 73 verse(s) in Quran in Abdullah Yusuf Ali translation.

(51) Is it not to Allah that sincere devotion is due? But those who take for protectors other than Allah (say): "We only serve them in order that they may bring us nearer to Allah." Truly Allah will judge between them in that wherein they differ. But Allah guides not such as are false and ungrateful.

(52) Say: "Verily, I am commanded to serve Allah with sincere devotion;

(53) Say: "It is Allah I serve, with my sincere (and exclusive) devotion:

(54) "serve ye what ye will besides him." Say: "Truly, those in loss are those who lose their own souls and their People on the Day of Judgment: Ah! that is indeed the (real and) evident Loss!

(55) Those who sustain the Throne (of Allah) and those around it Sing Glory and Praise to their Lord; believe in Him; and implore Forgiveness for those who believe: "Our Lord! Thy Reach is over all things, in Mercy and Knowledge. Forgive, then, those who turn in Repentance, and follow Thy Path; and preserve them from the Penalty of the Blazing Fire!

(56) "And preserve them from (all) ills; and any whom Thou dost preserve from ills that Day,- on them wilt Thou have bestowed Mercy indeed: and that will be truly (for them) the highest Achievement".

(57) And your Lord says: "Call on Me; I will answer your (Prayer): but those who are too arrogant to serve Me will surely find themselves in Hell - in humiliation!"

(58) Behold, the messengers came to them, from before them and behind them, (preaching): "serve none but Allah." They said, "If our Lord had so pleased, He would certainly have sent down angels (to preach). Now we reject your mission (altogether)."

(59) Among His Signs are the Night and the Day, and the Sun and the Moon. Do not prostrate to the sun and the moon, but prostrate to Allah, Who created them, if it is Him ye wish to serve.

(60) And they make into females angels who themselves serve Allah. Did they witness their creation? Their evidence will be recorded, and they will be called to account!
