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

(61) Nor will they there taste Death, except the first death; and He will preserve them from the Penalty of the Blazing Fire,-

(62) To be observed and commemorated by every devotee turning (to Allah).

(63) I have only created Jinns and men, that they may serve Me.

(64) Round about them will serve, (devoted) to them, young male servants (handsome) as Pearls well-guarded.

(65) Round about them will (serve) youths of perpetual (freshness),

(66) Hast thou not observed the Hypocrites say to their misbelieving brethren among the People of the Book? - "If ye are expelled, we too will go out with you, and we will never hearken to any one in your affair; and if ye are attacked (in fight) we will help you". But Allah is witness that they are indeed liars.

(67) Allah is He, than Whom there is no other god;- the Sovereign, the Holy One, the Source of Peace (and Perfection), the Guardian of Faith, the Preserver of Safety, the Exalted in Might, the Irresistible, the Supreme: Glory to Allah! (High is He) above the partners they attribute to Him.

(68) Do they not observe the birds above them, spreading their wings and folding them in? None can uphold them except (Allah) Most Gracious: Truly (Allah) Most Gracious: Truly it is He that watches over all things.

(69) And round about them will (serve) youths of perpetual (freshness): If thou seest them, thou wouldst think them scattered Pearls.

(70) And all things have We preserved on record.
