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

(191) Say (O Muhammad صلى الله عليه وسلم): "I am only a human being like you. It is revealed to me that your Ilah (God) is One Ilah (God - Allah), therefore take Straight Path to Him (with true Faith - Islamic Monotheism) and obedience to Him, and seek forgiveness of Him. And woe to Al-Mushrikun (the polytheists, idolaters, disbelievers in the Oneness of Allah).

(192) To Him (Alone) is referred the knowledge of the Hour. No fruit comes out of its sheath, nor does a female conceive nor brings forth (young), except by His Knowledge. And on the Day when He will call unto them (polytheists) (saying): "Where are My (so-called) partners (whom you did invent)?" They will say: "We inform You that none of us bears witness to it (that they are Your partners)!"

(193) And if Allah had willed, He could have made them one nation, but He admits whom He wills to His Mercy. And the Zalimun (polytheists and wrong-doers) will have neither a Wali (protector or guardian) nor a helper.

(194) And in whatsoever you differ, the decision thereof is with Allah (He is the ruling Judge). (And say O Muhammad صلى الله عليه و سلم to these polytheists:) Such is Allah, my Lord in Whom I put my trust, and to Him I turn (in all of my affairs and) in repentance.

(195) Or have they partners with Allah (false gods) who have instituted for them a religion which Allah has not ordained? And had it not been for a decisive Word (gone forth already), the matter would have been judged between them. And verily, for the Zalimun (polytheists and wrong-doers) there is a painful torment.

(196) You will see (on the Day of Resurrection), the Zalimun (polytheists and wrong-doers) fearful of that which they have earned, and it (Allah's Torment) will surely befall them. But those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous deeds (will be) in the flowering meadows of the Gardens (Paradise). They shall have whatsoever they desire with their Lord. That is the supreme Grace, (Paradise).

(197) And those who dispute (polytheists with Our Messenger Muhammad صلى الله عليه و سلم) as regards Our Ayat (proofs, signs, verses, etc. of Islamic Monotheism) may know that there is no place of refuge for them (from Allah's punishment) [Tafsir At-Tabari].

(198) The recompense for an evil is an evil like thereof; but whoever forgives and makes reconciliation, his reward is with Allah. Verily, He likes not the Zalimun (oppressors, polytheists, and wrong-doers).

(199) And whomsoever Allah sends astray, for him there is no Wali (protector, helper, guardian) after Him. And you will see the Zalimun (polytheists, wrong-doers, oppressors): when they behold the torment, they will say: "Is there any way of return (to the world)?"

(200) And you will see them brought forward to it (Hell) made humble by disgrace, (and) looking with stealthy glance. And those who believe will say: "Verily, the losers are they who lose themselves and their families on the Day of Resurrection. Verily, the Zalimun [i.e. Al-Kafirun (disbelievers in Allah, in His Oneness and in His Messenger صلى الله عليه و سلم, polytheists, wrong-doers)] will be in a lasting torment. (Tafsir At-Tabari).
