The word(s) "foe" appears 5 time(s) in 4 verse(s) in Quran in Mohsin Khan translation.

(1) And they say: "What is in the bellies of such and such cattle (milk or foetus) is for our males alone, and forbidden to our females (girls and women), but if it is born dead, then all have shares therein." He will punish them for their attribution (of such false orders to Allah). Verily, He is All-Wise, All-Knower. (Tafsir At-Tabari).

(2) And he entered the city at a time of unawareness of its people: and he found there two men fighting, - one of his party (his religion - from the Children of Israel), and the other of his foes. The man of his (own) party asked him for help against his foe, so Musa (Moses) struck him with his fist and killed him. He said: "This is of Shaitan's (Satan) doing: verily, he is a plain misleading enemy."

(3) Friends on that Day will be foes one to another except Al-Muttaqun (the pious. See V.2:2).

(4) And penetrating forthwith as one into the midst (of the foe).
