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

(21) When their eyes shall be turned towards the companions of the Fire, they will say: "Our Lord! send us not to the company of the wrong-doers."

(22) The companions of the Fire will call to the companions of the Garden: "Pour down to us water or anything that Allah doth provide for your sustenance." They will say: "Both these things hath Allah forbidden to those who rejected Him."
