The word(s) "enemies" appears 20 time(s) in 19 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) "For they are enemies to me; not so the Lord and Cherisher of the Worlds;

(12) On the Day that the enemies of Allah will be gathered together to the Fire, they will be marched in ranks.

(13) Such is the requital of the enemies of Allah,- the Fire: therein will be for them the Eternal Home: a (fit) requital, for that they were wont to reject Our Signs.

(14) O ye who believe! Take not my enemies and yours as friends (or protectors),- offering them (your) love, even though they have rejected the Truth that has come to you, and have (on the contrary) driven out the Prophet and yourselves (from your homes), (simply) because ye believe in Allah your Lord! If ye have come out to strive in My Way and to seek My Good Pleasure, (take them not as friends), holding secret converse of love (and friendship) with them: for I know full well all that ye conceal and all that ye reveal. And any of you that does this has strayed from the Straight Path.

(15) If they were to get the better of you, they would behave to you as enemies, and stretch forth their hands and their tongues against you for evil: and they desire that ye should reject the Truth.

(16) It may be that Allah will grant love (and friendship) between you and those whom ye (now) hold as enemies. For Allah has power (over all things); And Allah is Oft-Forgiving, Most Merciful.

(17) O ye who believe! Be ye helpers of Allah: As said Jesus the son of Mary to the Disciples, "Who will be my helpers to (the work of) Allah?" Said the disciples, "We are Allah's helpers!" then a portion of the Children of Israel believed, and a portion disbelieved: But We gave power to those who believed, against their enemies, and they became the ones that prevailed.

(18) When thou lookest at them, their exteriors please thee; and when they speak, thou listenest to their words. They are as (worthless as hollow) pieces of timber propped up, (unable to stand on their own). They think that every cry is against them. They are the enemies; so beware of them. The curse of Allah be on them! How are they deluded (away from the Truth)!

(19) O ye who believe! Truly, among your wives and your children are (some that are) enemies to yourselves: so beware of them! But if ye forgive and overlook, and cover up (their faults), verily Allah is Oft-Forgiving, Most Merciful.
