The word(s) "polytheism" appears 55 time(s) in 52 verse(s) in Quran in Mohsin Khan translation.

(31) And whoever brings an evil deed (i.e. Shirk - polytheism, disbelief in the Oneness of Allah and every evil sinful deed), they will be cast down (prone) on their faces in the Fire. (And it will be said to them) "Are you being recompensed anything except what you used to do?"

(32) But as for him who repented (from polytheism and sins), believed (in the Oneness of Allah, and in His Messenger Muhammad صلى الله عليه وسلم), and did righteous deeds (in the life of this world), then he will be among those who are successful.

(33) Whosoever brings good (Islamic Monotheism along with righteous deeds), he shall have the better thereof; and whosoever brings evil (polytheism along with evil deeds), then those who do evil deeds will only be requited for what they used to do.

(34) "Verily, you practise sodomy with men, and rob the wayfarer (travellers)! And practise Al-Munkar (disbelief and polytheism and every kind of evil wicked deed) in your meetings." But his people gave no answer except that they said: "Bring Allah's Torment upon us if you are one of the truthful."

(35) Recite (O Muhammad صلى الله عليه وسلم) what has been revealed to you of the Book (the Qur'an), and perform As-Salat (Iqamat-as-Salat). Verily, As-Salat (the prayer) prevents from Al-Fahsha' (i.e. great sins of every kind, unlawful sexual intercourse) and Al-Munkar (i.e. disbelief, polytheism, and every kind of evil wicked deed) and the remembering (praising) of (you by) Allah (in front of the angels) is greater indeed [than your remembering (praising) of Allah in prayers. And Allah knows what you do.

(36) Have they not seen that We have made (Makkah) a secure sanctuary, while men are being snatched away from all around them? Then do they believe in Batil (falsehood - polytheism, idols and all deities other than Allah), and deny (become ingrate for) the Graces of Allah?

(37) So on that Day no excuse of theirs will avail those who did wrong (by associating partners in worship with Allah, and by denying the Day of Resurrection), nor will they be allowed (then) to return to seek Allah's Pleasure (by having Islamic Faith with righteous deeds and by giving up polytheism, sins and crimes with repentance).

(38) "O my son! Aqim-As-Salat (perform As-Salat), enjoin (on people) Al-Ma'ruf - (Islamic Monotheism and all that is good), and forbid (people) from Al-Munkar (i.e. disbelief in the Oneness of Allah, polytheism of all kinds and all that is evil and bad), and bear with patience whatever befalls you. Verily, these are some of the important commandments (ordered by Allah with no exemption).

(39) And if the enemy had entered from all sides (of the city), and they had been exhorted to Al-Fitnah (i.e. to renegade from Islam to polytheism), they would surely have committed it and would have hesitated thereupon but little.

(40) He it is Who sends Salat (His blessings) on you, and His angels too (ask Allah to bless and forgive you), that He may bring you out from darkness (of disbelief and polytheism) into light (of Belief and Islamic Monotheism). And He is Ever Most Merciful to the believers.
