The word(s) "enemy" appears 38 time(s) in 33 verse(s) in Quran in Muhammad Habib Shakir translation.

(21) He said: Get forth you two therefrom, all (of you), one of you (is) enemy to another. So there will surely come to you guidance from Me, then whoever follows My guidance, he shall not go astray nor be unhappy;

(22) And thus have We made for every prophet an enemy from among the sinners and sufficient is your Lord as a Guide and a Helper.

(23) And Firon's family took him up that he might be an enemy and a grief for them; surely Firon and Haman and their hosts were wrongdoers.

(24) And he went into the city at a time of unvigilance on the part of its people, so he found therein two men fighting, one being of his party and the other of his foes, and he who was of his party cried out to him for help against him who was of his enemies, so Musa struck him with his fist and killed him. He said: This is on account of the Shaitan's doing; surely he is an enemy, openly leading astray.

(25) So when he desired to seize him who was an enemy to them both, he said: O Musa! do you intend to kill me as you killed a person yesterday? You desire nothing but that you should be a tyrant in the land, and you do not desire to be of those who act aright.

(26) Surely the Shaitan is your enemy, so take him for an enemy; he only invites his party that they may be inmates of the burning

(27) Did I not charge you, O children of Adam! that you should not serve the Shaitan? Surely he is your open enemy,

(28) And let not the Shaitan prevent you; surely he is your open enemy.

(29) O you who believe! do not take My enemy and your enemy for friends: would you offer them love while they deny what has come to you of the truth, driving out the Apostle and yourselves because you believe in Allah, your Lord? If you go forth struggling hard in My path and seeking My pleasure, would you manifest love to them? And I know what you conceal and what you manifest; and whoever of you does this, he indeed has gone astray from the straight path.

(30) O you who believe! be helpers (in the cause) of Allah, as~ Isa son of Marium said to (his) disciples: Who are my helpers in the cause of Allah? The disciples said: We are helpers (in the cause) of Allah. So a party of the children of Israel believed and another party disbelieved; then We aided those who believed against their enemy, and they became uppermost.
