The word(s) "foe" appears 13 time(s) in 13 verse(s) in Quran in Muhammad Pickthal translation.

(1) But Satan caused them to deflect therefrom and expelled them from the (happy) state in which they were; and We said: Fall down, one of you a foe unto the other! There shall be for you on earth a habitation and provision for a time.

(2) And of the cattle (He produceth) some for burdens, some for food. Eat of that which Allah hath bestowed upon you, and follow not the footsteps of the devil, for lo! he is an open foe to you.

(3) He said: Go down (from hence), one of you a foe unto the other. There will be for you on earth a habitation and provision for a while.

(4) If Allah bring thee back (from the campaign) unto a party of them and they ask of thee leave to go out (to fight), then say unto them: Ye shall never more go out with me nor fight with me against a foe. Ye were content with sitting still the first time. So sit still, with the useless.

(5) He said: O my dear son! Tell not thy brethren of thy vision, lest they plot a plot against thee. Lo! Satan is for man an open foe.

(6) Tell My bondmen to speak that which is kindlier. Lo! the devil soweth discord among them. Lo! the devil is for man an open foe.

(7) He said: Go down hence, both of you, one of you a foe unto the other. But when there come unto you from Me a guidance, then whoso followeth My guidance, he will not go astray nor come to grief.

(8) And verily they had already sworn unto Allah that they would not turn their backs (to the foe). An oath to Allah must be answered for.

(9) Did I not charge you, O ye sons of Adam, that ye worship not the devil - Lo! he is your open foe! -

(10) Friends on that day will be foes one to another, save those who kept their duty (to Allah).
