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

(91) Therefore proclaim openly (Allah's Message - Islamic Monotheism) that which you are commanded, and turn away from Al-Mushrikun (polytheists, idolaters, and disbelievers - See V.2:105).

(92) The Event (the Hour or the punishment of disbelievers and polytheists or the Islamic laws or commandments) ordained by Allah will come to pass, so seek not to hasten it. Glorified and Exalted be He above all that they associate as partners with Him.

(93) Do they (the disbelievers and polytheists) await but that the angels should come to them [to take away their souls (at death)], or there should come the command (i.e. the torment or the Day of Resurrection) of your Lord? Thus did those before them. And Allah wronged them not, but they used to wrong themselves.

(94) His power is only over those who obey and follow him (Satan), and those who join partners with Him (Allah i.e. those who are Mushrikun i.e. polytheists. See Verse 6:121).

(95) And indeed We know that they (polytheists and pagans) say: "It is only a human being who teaches him (Muhammad صلى الله عليه و سلم)." The tongue of the man they refer to is foreign, while this (the Qur'an) is a clear Arabic tongue.

(96) And verily, there had come unto them a Messenger (Muhammad صلى الله عليه و سلم) from among themselves, but they denied him, so the torment overtook them while they were Zalimun (polytheists and wrong-doers).

(97) Verily, Ibrahim (Abraham) was an Ummah (a leader having all the good righteous qualities), or a nation, obedient to Allah, Hanif (i.e. to worship none but Allah), and he was not one of those who were Al-Mushrikun (polytheists, idolaters, disbelievers in the Oneness of Allah, and those who joined partners with Allah).

(98) Then, We have sent the revelation to you (O Muhammad صلى الله عليه و سلم saying): "Follow the religion of Ibrahim (Abraham) Hanif (Islamic Monotheism - to worship none but Allah) and he was not of the Mushrikun (polytheists, idolaters and disbelievers).

(99) And endure you patiently (O Muhammad صلى الله عليه و سلم), your patience is not but from Allah. And grieve not over them (polytheists and pagans), and be not distressed because of what they plot.

(100) Say (O Muhammad صلى الله عليه و سلم to these polytheists, pagans): "If there had been other alihah (gods) along with Him as they assert, then they would certainly have sought out a way to the Lord of the Throne (seeking His Pleasures and to be near to Him).
