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

(41) And We rained down on them a rain (of stones). Then see what was the end of the Mujrimun (criminals, polytheists and sinners).

(42) So We sent on them: the flood, the locusts, the lice, the frogs, and the blood (as a succession of) manifest signs, yet they remained arrogant, and they were of those people who were Mujrimun (criminals, polytheists, sinners).

(43) It is He Who has created you from a single person (Adam), and (then) He has created from him his wife [Hawwa' (Eve)], in order that he might enjoy the pleasure of living with her. When he (a polytheist from Adam's offspring - as stated by Ibn Kathir in his Tafsir) had sexual relation with her (the polytheist's wife), she became pregnant and she carried it about lightly. Then when it became heavy, they both invoked Allah, their Lord (saying): "If You give us a Salih (good in every aspect) child, we shall indeed be among the grateful."

(44) But when He gave them (the polytheist and his wife) a Salih (good in every aspect) child, they ascribed partners to Him (Allah) in that which He has given to them. High be Allah, Exalted above all that they ascribe as partners to Him. (Tafsir Ibn Kathir).

(45) That He might cause the truth to triumph and bring falsehood to nothing, even though the Mujrimun (disbelievers, polytheists, sinners, criminals) hate it.

(46) In order that Allah may distinguish the wicked (disbelievers, polytheists and doers of evil deeds) from the good (believers of Islamic Monotheism and doers of righteous deeds), and put the wicked (disbelievers, polytheists and doers of evil deeds) one over another, heap them together and cast them into Hell. Those! it is they who are the losers.

(47) Similar to the behaviour of the people of Fir'aun (Pharaoh), and those before them. They belied the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of their Lord, so We destroyed them for their sins, and We drowned the people of Fir'aun (Pharaoh) for they were all Zalimun (polytheists and wrong-doers).

(48) Freedom from (all) obligations (is declared) from Allah and His Messenger (صلى الله عليه وسلم) to those of the Mushrikun (polytheists, pagans, idolaters, disbelievers in the Oneness of Allah), with whom you made a treaty.

(49) And if anyone of the Mushrikun (polytheists, idolaters, pagans, disbelievers in the Oneness of Allah) seeks your protection, then grant him protection so that he may hear the Word of Allah (the Qur'an), and then escort him to where he can be secure, that is because they are men who know not.

(50) How can there be a covenant with Allah and with His Messenger for the Mushrikun (polytheists, idolaters, pagans, disbelievers in the Oneness of Allah) except those with whom you made a covenant near Al-Masjid-al-Haram (at Makkah)? So long as they are true to you, stand you true to them. Verily, Allah loves Al-Muttaqun (the pious - See V.2:2).
