The word(s) "companion" appears 98 time(s) in 88 verse(s) in Quran in Saheeh International translation.

(1) And those who disbelieve and deny Our signs - those will be companions of the Fire; they will abide therein eternally."

(2) Yes, whoever earns evil and his sin has encompassed him - those are the companions of the Fire; they will abide therein eternally.

(3) But they who believe and do righteous deeds - those are the companions of Paradise; they will abide therein eternally.

(4) Indeed, We have sent you, [O Muhammad], with the truth as a bringer of good tidings and a warner, and you will not be asked about the companions of Hellfire.

(5) They ask you about the sacred month - about fighting therein. Say, "Fighting therein is great [sin], but averting [people] from the way of Allah and disbelief in Him and [preventing access to] al-Masjid al-Haram and the expulsion of its people therefrom are greater [evil] in the sight of Allah. And fitnah is greater than killing." And they will continue to fight you until they turn you back from your religion if they are able. And whoever of you reverts from his religion [to disbelief] and dies while he is a disbeliever - for those, their deeds have become worthless in this world and the Hereafter, and those are the companions of the Fire, they will abide therein eternally.

(6) Allah is the ally of those who believe. He brings them out from darknesses into the light. And those who disbelieve - their allies are Taghut. They take them out of the light into darknesses. Those are the companions of the Fire; they will abide eternally therein.

(7) Those who consume interest cannot stand [on the Day of Resurrection] except as one stands who is being beaten by Satan into insanity. That is because they say, "Trade is [just] like interest." But Allah has permitted trade and has forbidden interest. So whoever has received an admonition from his Lord and desists may have what is past, and his affair rests with Allah. But whoever returns to [dealing in interest or usury] - those are the companions of the Fire; they will abide eternally therein.

(8) Indeed, those who disbelieve - never will their wealth or their children avail them against Allah at all, and those are the companions of the Fire; they will abide therein eternally.

(9) Worship Allah and associate nothing with Him, and to parents do good, and to relatives, orphans, the needy, the near neighbor, the neighbor farther away, the companion at your side, the traveler, and those whom your right hands possess. Indeed, Allah does not like those who are self-deluding and boastful.

(10) And [also] those who spend of their wealth to be seen by the people and believe not in Allah nor in the Last Day. And he to whom Satan is a companion - then evil is he as a companion.
