The word(s) "serve" appears 118 time(s) in 107 verse(s) in Quran in Muhammad Habib Shakir translation.

(91) Say: If the Beneficent Allah has a son, I am the foremost of those who serve.

(92) And mention the brother of Ad; when he warned his people in the sandy plains,-- and indeed warners came before him and after him-- saying serve none but Allah; surely I fear for you the punishment of a grievous day.

(93) We know indeed what the earth diminishes of them, and with Us is a writing that preserves.

(94) And I have not created the jinn and the men except that they should serve Me.

(95) So make obeisance to Allah and serve (Him).

(96) Then We made Our apostles to follow in their footsteps, and We sent Isa son of Marium afterwards, and We gave him the Injeel, and We put in the hearts of those who followed him kindness and mercy; and (as for) monkery, they innovated it-- We did not prescribe it to them-- only to seek Allah's pleasure, but they did not observe it with its due observance; so We gave to those of them who believed their reward, and most of them are transgressors.

(97) They make their oaths to serve as a cover so they turn away from Allah's way; therefore they shall have an abasing chastisement.

(98) And those who made their abode in the city and in the faith before them love those who have fled to them, and do not find in their hearts a need of what they are given, and prefer (them) before themselves though poverty may afflict them, and whoever is preserved from the niggardliness of his soul, these it is that are the successful ones.

(99) Indeed, there is for you a good example in Ibrahim and those with him when they said to their people: Surely we are clear of you and of what you serve besides Allah; we declare ourselves to be clear of you, and enmity and hatred have appeared between us and you forever until you believe in Allah alone-- but not in what Ibrahim said to his father: I would certainly ask forgiveness for you, and I do not control for you aught from Allah-- Our Lord! on Thee do we rely, and to Thee do we turn, and to Thee is the eventual coming:

(100) The likeness of those who were charged with the Taurat, then they did not observe it, is as the likeness of the ass bearing books, evil is the likeness of the people who reject the communications of Allah; and Allah does not guide the unjust people.
