The word(s) "companion" appears 33 time(s) in 32 verse(s) in Quran in Mohsin Khan translation.

(21) Say (to them O Muhammad صلى الله عليه وسلم): "I exhort you to one (thing) only: that you stand up for Allah's sake in pairs and singly, and reflect (within yourselves the life history of the Prophet صلى الله عليه وسلم): there is no madness in your companion (Muhammad صلى الله عليه وسلم). He is only a warner to you in face of a severe torment."

(22) (It will be said to the angels): "Assemble those who did wrong, together with their companions (from the devils) and what they used to worship,

(23) A speaker of them will say: "Verily, I had a companion (in the world),

(24) And We have assigned for them (devils) intimate companions (in this world), who have made fair-seeming to them, what was before them (evil deeds which they were doing in the present worldly life and disbelief in the Reckoning and the Resurrection) and what was behind them (denial of the matters in the coming life of the Hereafter as regards punishment or reward). And the Word (i.e. the torment) is justified against them as it was justified against those who were among the previous generations of jinn and men that had passed away before them. Indeed they (all) were the losers.

(25) And whosoever turns away blindly from the remembrance of the Most Gracious (Allah) (i.e. this Qur'an and worship of Allah), We appoint for him Shaitan (Satan - devil) to be a Qarin (a companion) to him.

(26) Till, when (such a one) comes to Us, he says [to his Qarin (Satan / devil companion)] "Would that between me and you were the distance of the two easts (or the east and west)" - a worst (type of) companion (indeed)!

(27) Indeed Allah shall fulfil the true vision which He showed to His Messenger (صلى الله عليه وسلم) [i.e. the Prophet صلى الله عليه وسلم saw a dream that he has entered Makkah along with his companions, having their (head) hair shaved and cut short] in very truth. Certainly, you shall enter Al-Masjid-al-Haram, if Allah wills, secure, (some) having your heads shaved, and (some) having your head hair cut short, having no fear. He knew what you knew not, and He granted besides that a near victory.

(28) And his companion (angel) will say: "Here is (this Record) ready with me!"

(29) His companion (Satan - devil)] will say: "Our Lord! I did not push him to transgression, (in disbelief, oppression, and evil deeds) but he was himself in error far astray."

(30) Your companion (Muhammad صلى الله عليه وسلم) has neither gone astray nor has erred.
