The word(s) "companion" appears 99 time(s) in 89 verse(s) in Quran in Abdullah Yusuf Ali translation.

(31) If thou dost marvel (at their want of faith), strange is their saying: "When we are (actually) dust, shall we indeed then be in a creation renewed?" They are those who deny their Lord! They are those round whose necks will be yokes (of servitude): they will be companions of the Fire, to dwell therein (for aye)!

(32) And the companions of the Wood were also wrong-doers;

(33) The companions of the Rocky Tract also rejected the messengers:

(34) And Allah has made for you mates (and companions) of your own nature, and made for you, out of them, sons and daughters and grandchildren, and provided for you sustenance of the best: will they then believe in vain things, and be ungrateful for Allah's favours?-

(35) Or dost thou reflect that the companions of the Cave and of the Inscription were wonders among Our Sign?

(36) (Abundant) was the produce this man had: he said to his companion, in the course of a mutual argument: "more wealth have I than you, and more honour and power in (my following of) men."

(37) His companion said to him, in the course of the argument with him: "Dost thou deny Him Who created thee out of dust, then out of a sperm-drop, then fashioned thee into a man?

(38) (Perhaps) they call on one whose hurt is nearer than his profit: evil, indeed, is the patron, and evil the companion (or help)!

(39) And the companions of the Madyan People; and Moses was rejected (in the same way). But I granted respite to the Unbelievers, and (only) after that did I punish them: but how (terrible) was my rejection (of them)!

(40) "But those who strive against Our Signs, to frustrate them,- they will be companions of the Fire."
