The word(s) "polytheist" appears 243 time(s) in 236 verse(s) in Quran in Mohsin Khan translation.

(131) The adulterer-fornicator marries not but an adulteress-fornicatress or a Mushrikah, and the adulteress-fornicatress none marries her except an adulterer-fornicator or a Muskrik [and that means that the man who agrees to marry (have a sexual relation with) a Mushrikah (female polytheist, pagan or idolatress) or a prostitute, then surely he is either an adulterer-fornicator, or a Mushrik (polytheist, pagan or idolater). And the woman who agrees to marry (have a sexual relation with) a Mushrik (polytheist, pagan or idolater) or an adulterer-fornicator, then she is either a prostitute or a Mushrikah (female polytheist, pagan, or idolatress)]. Such a thing is forbidden to the believers (of Islamic Monotheism).

(132) Is there a disease in their hearts? Or do they doubt or fear lest Allah and His Messenger (صلى الله عليه وسلم) should wrong them in judgement. Nay, it is they themselves who are the Zalimun (polytheists, hypocrites and wrong-doers).

(133) "Or (why) has not a treasure been granted to him, or why has he not a garden whereof he may eat?" And the Zalimun (polytheists and wrong-doers) say: "You follow none but a man bewitched."

(134) Thus they (false gods - all deities other than Allah) will belie you (polytheists) regarding what you say (that they are gods besides Allah): then you can neither avert (the punishment), nor get help. And whoever among you does wrong (i.e. sets up rivals to Allah), We shall make him taste a great torment.

(135) On the Day they will see the angels - no glad tidings will there be for the Mujrimun (criminals, disbelievers, polytheists, sinners) that day. And they (angels) will say: "All kinds of glad tidings are forbidden to you," [none will be allowed to enter Paradise except the one who said: La ilaha illallah, "(none has the right to be worshipped but Allah) and acted practically on its legal orders and obligations. See the footnote of V.2:193)].

(136) And We shall turn to whatever deeds they (disbelievers, polytheists, sinners) did, and We shall make such deeds as scattered floating particles of dust.

(137) And (remember) the Day when the Zalim (wrong-doer, oppressor, polytheist) will bite at his hands, he will say: "Oh! Would that I had taken a path with the Messenger (Muhammad صلى الله عليه وسلم).

(138) Thus have We made for every Prophet an enemy among the Mujrimun (disbelievers, polytheists, criminals). But Sufficient is your Lord as a Guide and Helper.

(139) And Nuh's (Noah) people, when they denied the Messengers, We drowned them, and We made them as a sign for mankind. And We have prepared a painful torment for the Zalimun (polytheists and wrong-doers).

(140) And they (disbelievers, polytheists) worship besides Allah that which can neither profit them nor harm them; and the disbeliever is ever a helper (of the Satan) against his Lord.
