In Islam, Shirk (Arabic: شرك širk) is the sin of idolatry or polytheism (i.e., the deification or worship of anyone or anything besides Allah). Islam teaches that God does not share His divine attributes with any partner. Associating partners with God is disallowed according to the Islamic doctrine of Tawhid (monotheism). Mušrikūn مشركون (pl. of mušrik مشرك) are those who practice shirk, which literally means "association" and refers to accepting other gods and divinities alongside God (as God's "associates"). The Qur'an considers shirk as a sin that will not be forgiven if a person dies without repenting of it.
The word širk comes from the Arabic root Š-R-K (ش ر ك), with the general meaning of "to share". In the context of the Quran, the particular sense of "sharing as an equal partner" is usually understood, so that polytheism means "attributing a partner to Allah". In the Quran, shirk and the related word mušrikūn (مشركون)—those who commit shirk and plot against Islam—often refer to the enemies of Islam (as in At-Tawbah verses 9:1–15).: 9:1–15
According to the Encyclopedia of Islam, the Quran states "twice", in surah an-Nisa, verses 48 and 116, "that God can pardon all sins save one", that of shirk ("associationism"). Islamic commentators on the Quran have emphasized that pre-Islamic Arabic idolatry made a number of godlings, most memorably the three goddesses Manāt, Al-Lāt and Al-‘Uzzá, equal associates of Allah (as the Quran discusses in the 53rd surat) and the word mushrikūn (singular: mushrik) is often translated into English as "polytheists".
The Quran and what the people of Nuh's community would say in an effort by the idolaters to ignore and mock Nuh. "They (idolaters) have said: "You shall not leave your gods nor shall you leave Wadd, nor Suwa', nor Yaghuth, nor Ya'uq nor Nasr." (Quran 71:23): 71:23
Other forms of shirk include the worship of wealth and other material objects. This is pointed out in the Quran in Al-A'raf in one of the stories of the Children of Israel, when they took a calf made of gold for worship, and for which Moses ordered them to repent.
Another form of shirk mentioned in the Quran At-Tawbah is to take scholars of religion, monks, divines, or religious lawyers as Lord(s) in practice by following their doctrines, and/or by following their rulings on what is lawful when it is at variance to the law or doctrines prescribed by Allah's revelation.
And do not eat of that on which Allah's name has not been mentioned, and that is most surely a transgression; and most surely the Shaitans suggest to their friends that they should contend with you; and if you obey them, you shall most surely be polytheists.
— Quran, sura «№6», ayah №121.(translated by Shakir)
Medieval Muslim and Jewish philosophers identified belief in the Trinity with the heresy of shirk, in Arabic, (or shituf in Hebrew), meaning "associationism", in limiting the infinity of God by associating his divinity with physical existence.
In a theological context one commits shirk by associating some lesser being with Allah. This sin is committed if one imagines that there is a partner with Allah whom it is suitable to worship. It is stated in the Quran: "Allah forgives not that partners should be set up with Him, but He forgives anything else, to whom He pleases, to set up partners with Allah is to devise a sin most heinous indeed" (Quran An-Nisa 4:48).: 4:48
Some followers of a sufistic interpretation of Islam tend to regard the belief in any other power than God as a type of polytheism (shirk). This does not only include false gods, but also the belief in other sources of existence. Beliefs usually accepted by monotheism, such as a devil as a source of evil or free will as source for God's creation's own responsibilities, are equated with beliefs in other powers than God, and therefore denounced.
The status of the People of the Book (ahl al-kitab), particularly Jews and Christians, with respect to the Islamic notions of unbelief is not clearcut. Charles Adams writes that the Quran reproaches the People of the Book with kufr for rejecting Muhammad's message when they should have been the first to accept it as possessors of earlier revelations, and singles out Christians for disregarding the evidence of God's unity. The Quranic verse Al-Ma'idah 5:73: 5:73 ("Certainly they disbelieve [kafara] who say: God is the third of three"), among other verses, has been traditionally understood in Islam as rejection of the Christian Trinity doctrine, though modern scholarship has suggested alternative interpretations.[note 1] Other Quranic verses strongly deny the deity of Jesus Christ, son of Mary and reproach the people who treat Jesus as equal with God as disbelievers who will be doomed to eternal punishment in Hell. The Quran also does not recognize the attribute of Jesus as the Son of God or God himself, it respects Jesus as a prophet and messenger of God sent to children of Israel. Some Muslim thinkers such as Mohamed Talbi have viewed the most extreme Quranic presentations of the dogmas of the Trinity and divinity of Jesus (Al-Ma'idah 5:19, 5:75-76, 5:119) as non-Christian formulas that were rejected by the Church.
Cyril Glasse criticizes the use of kafirun [pl. of kafir] to describe Christians as "loose usage". According to the Encyclopaedia of Islam, in traditional Islamic jurisprudence, ahl al-kitab are "usually regarded more leniently than other kuffar [pl. of kafir]..." and "in theory" a Muslim commits a punishable offense if he says to a Jew or a Christian: "Thou unbeliever".
Historically, People of the Book permanently residing under Islamic rule were entitled to a special status known as dhimmi, while those visiting Muslim lands received a different status known as musta'min.
After the eighteenth century, with the rise of Wahhabism, shirk was applied to a far wider range, when before, such as participating in political affairs alien to Islam, or to adhere to religious customs, believed not to root in Islam.
Greater and lesser shirkEdit
- Greater shirk (Shirk-al-Akbar): Open and apparent
- Lesser shirk (Shirk-al-Asghar): Concealed or hidden
Greater shirk or Shirke-al-Akbar means open polytheism and has been described in two forms:
- To associate anyone with Allah as his partner (to believe in more than one god).
- To associate Allah's attributes with someone else. (Attributing, considering, or portraying Allah's knowledge or might to being those of anyone else)
Other interpretations divide greater shirk into three main categories. Shirk can be committed by acting against the three different categories.
This category of shirk refers to either the belief that others share Allah's lordship over creation as his equal or near equal, or to the belief that there exists no lord over creation at all.
- Shirk by association: This is the shirk concerned with associating "others" with Allah.
- Shirk by negation: This is shirk in Rubūbīyah (Lordship).
Al-Asma wa's-Sifat (names and attributes)Edit
Shirk in this category includes both the non-believer practices of giving Allah the attributes of his creation as well as the act of giving created beings Allah's names and attributes.
- Shirk by humanization: In this aspect of shirk, Allah is given the form and qualities of human beings and animals. Due to man's superiority over animals, the human form is more commonly used by idolaters to represent Allah in creation. Consequently, the image of the creator is often painted, moulded or carved in the shape of human beings possessing the physical features of those who worship them.
- Shirk by deification: This form of shirk relates to cases where created beings or things are given or claim Allah's names or his attributes. For example, it was the practice of the ancient Arabs to worship idols whose names were derived from the names of Allah. Their main three deities were; Al-lāt (taken from Allah's name al-Elah), al-'Uzza (taken from al-'Aziz), and al-Manat (taken from al-Mannan). During the era of Muhammad there was also a man in a region of Arabia called Yamamah, who claimed to be a prophet and took the name Rahman which, in Islam, belongs only to Allah.
In this category of shirk, acts of worship are directed to others besides Allah and the reward for worship is sought from the creation instead of the creator. As in the case of the previous categories, shirk in al-'Ibadah has two main aspects.
This form of shirk occurs when any act of worship is directed to someone else besides Allah. It represents the most obvious form of idolatry, against which the prophets were specifically sent by Allah, calling the masses of mankind to give it up. Examples of this shirk are asking for forgiveness, admittance to paradise, etc. that only Allah can provide, from others besides Allah.
Lesser shirk or Shirke-e-Asghar means hidden polytheism. A person commits hidden polytheism when he professes tawhid (there is no god except Allah) but his thoughts and actions do not reflect his belief.
"One who offers the ritual prayers in an ostentatious way is a polytheist. One who keeps the fast, or gives alms, or performs the Hajj to show the public his righteousness or to earn good name is a polytheist."— Sayyed Qasim Mujtaba Moosavi Kamoonpuri 
Mahmud ibn Lubayd reported, "Allah's messenger said: 'The thing I fear for you the most is ash-Shirk al-Asghar.'"
- The companions asked, "O messenger of Allah, what is that?"
- He replied, "Ar-Riya (showing off), for verily Allah will say on the Day of Resurrection when people are receiving their rewards, 'Go to those for whom you were showing off in the material world and see if you can find any reward from them.'"
Mahmud ibn Lubayd also said, "The Prophet came out and announced, 'O people, beware of secret Shirk!'"
- The people asked, "O messenger of Allah, what is secret Shirk?"
- He replied, "When a man gets up to pray and strives to beautify his prayer because people are looking at him; that is secret Shirk."
According to Muhammad ibn Abd al-Wahhab, Ibn Mas’ood, one of Muhammad's companions, said: "That I should swear by Allah upon a lie is more preferable to me than that I should swear by another upon the truth."
- That this verse criticizes a deviant form of Trinitarian belief which overstressed distinctiveness of the three persons at the expense of their unity. Modern scholars have also interpreted it as a reference to Jesus, who was often called "the third of three" in Syriac literature and as an intentional over-simplification of Christian doctrine intended to highlight its weakness from a strictly monotheistic perspective.

- "Forgiveness for Shirk".
The meaning of the verse is that whoever dies while a Mushrik (polytheist) Allah will not forgive him and he will surely be punished for this sin, i.e. he will remain in Hell-fire forever. As for the person who repents, Allah forgives his previous Shirk.
