Duties and Practices

Five Pillars

The Five Pillars of Islam are five practices essential to Sunni Islam. Shi'a Muslims subscribe to different sets of pillars which substantially overlap with the Five Pillars. They are as follows:

• The shahadah, which is the basic creed or tenet of Islam: "'ašhadu 'al-lā ilāha illā-llāhu wa 'ašhadu 'anna muħammadan rasūlu-llāh", or "I testify that there is none worthy of worship except God and I testify that Muhammad is the Messenger of God." This testament is a foundation for all other beliefs and practices in Islam. Muslims must repeat the shahadah in prayer, and non-Muslims wishing to convert to Islam are required to recite the creed.
• Salah, or ritual prayer, which must be performed five times a day. Each salah is done facing towards the Kaaba in Mecca. Salah is intended to focus the mind on God, and is seen as a personal communication with him that expresses gratitude and worship. Salah is compulsory but flexibility in the specifics is allowed depending on circumstances. In many Muslim countries, reminders called Adhan (call to prayer) are broadcast publicly from local mosques at the appropriate times. The prayers are recited in the Arabic language, and consist of verses from the Qur'an.
• Zakat, or alms-giving. This is the practice of giving based on accumulated wealth, and is obligatory for all Muslims who can afford it. A fixed portion is spent to help the poor or needy, and also to assist the spread of Islam. The zakat is considered a religious obligation (as opposed to voluntary charity) that the well-off owe to the needy because their wealth is seen as a "trust from God's bounty". The Qur'an and the hadith also suggest a Muslim give even more as an act of voluntary alms-giving (sadaqah).
• Sawm, or fasting during the month of Ramadan. Muslims must not eat or drink (among other things) from dawn to dusk during this month, and must be mindful of other sins. The fast is to encourage a feeling of nearness to God, and during it Muslims should express their gratitude for and dependence on him, atone for their past sins, and think of the needy. Sawm is not obligatory for several groups for whom it would constitute an undue burden. For others, flexibility is allowed depending on circumstances, but missed fasts usually must be made up quickly. Some Muslim groups do not fast during Ramadan, and instead have fasts different times of the year.
• The Hajj, which is the pilgrimage during the Islamic month of Dhu al-Hijjah in the city of Mecca. Every able-bodied Muslim who can afford it must make the pilgrimage to Mecca at least once in his or her lifetime. When the pilgrim is about ten kilometers from Mecca, he must dress in Ihram clothing, which consists of two white seamless sheets. Rituals of the Hajj include walking seven times around the Kaaba, touching the Black Stone, running seven times between Mount Safa and Mount Marwah, and symbolically stoning the Devil in Mina. The pilgrim, or the hajji, is honored in his or her community, although Islamic teachers say that the Hajj should be an expression of devotion to God instead of a means to gain social standing.

Law

The Sharia (literally: "the path leading to the watering place") is Islamic law formed by traditional Islamic scholarship, which most Muslim groups adhere to. In Islam, Sharia is the expression of the divine will, and "constitutes a system of duties that are incumbent upon a Muslim by virtue of his religious belief".

Islamic law covers all aspects of life, from matters of state, like governance and foreign relations, to issues of daily living. The Qur'an defines hudud as the punishments for five specific crimes: unlawful intercourse, false accusation of unlawful intercourse, consumption of alcohol, theft, and highway robbery. The Qur'an and Sunnah also contain laws of inheritance, marriage, and restitution for injuries and murder, as well as rules for fasting, charity, and prayer. However, these prescriptions and prohibitions may be broad, so their application in practice varies. Islamic scholars (known as ulema) have elaborated systems of law on the basis of these rules and their interpretations.

Fiqh, or "jurisprudence", is defined as the knowledge of the practical rules of the religion. The method Islamic jurists use to derive rulings is known as usul al-fiqh ("legal theory", or "principles of jurisprudence"). According to Islamic legal theory, law has four fundamental roots, which are given precedence in this order: the Qur'an, the Sunnah (actions and sayings of Muhammad), the consensus of the Muslim jurists (ijma), and analogical reasoning (qiyas). For early Islamic jurists, theory was less important than pragmatic application of the law. In the 9th century, the jurist ash-Shafi'i provided a theoretical basis for Islamic law by codifying the principles of jurisprudence (including the four fundamental roots) in his book ar-Risālah.

Religion and state

Mainstream Islamic law does not distinguish between "matters of church" and "matters of state"; the ulema function as both jurists and theologians. In practice, Islamic rulers frequently bypassed the Sharia courts with a parallel system of so-called "Grievance courts" over which they had sole control. As the Muslim world came into contact with Western secular ideals, Muslim societies responded in different ways. Turkey has been governed as a secular state ever since the reforms of Mustafa Kemal Atatürk. In contrast, the 1979 Iranian Revolution replaced a mostly secular regime with an Islamic republic led by the Ayatollah Khomeini.

Etiquette and diet

Many practices fall in the category of adab, or Islamic etiquette. This includes greeting others with "as-salamu `alaykum" ("peace be unto you"), saying bismillah ("in the name of God") before meals, and using only the right hand for eating and drinking. Islamic hygienic practices mainly fall into the category of personal cleanliness and health, such as the circumcision of male offspring. Islamic burial rituals include saying the Salat al-Janazah ("funeral prayer") over the bathed and enshrouded dead body, and burying it in a grave. Muslims, as with Jews, are restricted in their diet. Prohibited foods include pork products, blood, carrion, and alcohol. All meat must come from a herbivorous animal slaughtered in the name of God by a Muslim, Jew, or Christian, with the exception of game that one has hunted or fished for oneself. Food permissible for Muslims is known as halal food.

Jihad

Jihad means "to strive or struggle" (in the way of God) and is considered the "Sixth Pillar of Islam" by a minority of Sunni Muslim authorities. Jihad, in its broadest sense, is classically defined as "exerting one's utmost power, efforts, endeavors, or ability in contending with an object of disapprobation." Depending on the object being a visible enemy, the devil, and aspects of one's own self, different categories of Jihad are defined. Jihad when used without any qualifier is understood in its military aspect. Jihad also refers to one's striving to attain religious and moral perfection. Some Muslim authorities, especially among the Shi'a and Sufis, distinguish between the "greater jihad", which pertains to spiritual self-perfection, and the "lesser jihad", defined as warfare.

Within Islamic jurisprudence, jihad is usually taken to mean military exertion against non-Muslim combatants in the defense or expansion of the Islamic state, the ultimate purpose of which is to universalize Islam. Jihad, the only form of warfare permissible in Islamic law, may be declared against apostates, rebels, highway robbers, violent groups, un-Islamic leaders or states which refuse to submit to the authority of Islam. Most Muslims today interpret Jihad as only a defensive form of warfare: the external Jihad includes a struggle to make the Islamic societies conform to the Islamic norms of justice.

Under most circumstances and for most Muslims, jihad is a collective duty (fard kifaya): its performance by some individuals exempts the others. Only for those vested with authority, especially the sovereign (imam), does jihad become an individual duty. For the rest of the populace, this happens only in the case of a general mobilization. For most Shias, offensive jihad can only be declared by a divinely appointed leader of the Muslim community, and as such is suspended since Muhammad al-Mahdi's occultation in 868 AD.
