Islam is a monotheistic religion based upon the Qur’an, which adherents believe was sent by God through Muhammad. Followers of Islam, known as Muslims, believe Muhammad to have been God’s final prophet; most of them see the historic record of the actions and teachings of the Prophet Muhammad related in the Sunnah and Hadith as indispensable tools for interpreting the Qur’an.
Like Judaism and Christianity, Islam is classified as an Abrahamic religion. It is estimated that there are 1.4 billion adherents, making Islam the second-largest religion in the world. Secular historians place Islam’s beginnings during the late 7th century in Arabia. Under the leadership of Muhammad and his successors, Islam rapidly spread by religious conversion and military conquest.
Muslims believe that God revealed his direct word for humanity to Muhammad (c. 570- July 6, 632) through the angel Gabriel and earlier prophets, including Adam, Noah, Abraham, Moses, and Jesus. Muslims believe that Muhammad is the last prophet, based on the Qur’anic phrase “Seal of the Prophets” and sayings of the prophet of Islam himself, and that his teachings for humanity will last until the Day of the Resurrection. Muslims assert that the main written record of revelation to humanity is the Qur’an, which is flawless, immutable, and which Muslims believe is the final revelation of God to humanity.
Islam includes many religious practices. Adherents are generally required to observe the Five Pillars of Islam, which are five duties that unite Muslims into a community. In addition to the Five Pillars, Islamic law has developed a tradition of rulings that touch on virtually all aspects of life and society. This tradition encompasses everything from practical matters like dietary laws and banking to warfare and welfare.
Almost all Muslims belong to one of two major denominations, the Sunni (85%) and Shi’a (15%). The schism developed in the late 7th century following disagreements over the religious and political leadership of the Muslim community. Islam is the predominant religion in Africa and the Middle East, as well as in major parts of Asia. Large communities are also found in China, the Balkan Peninsula in Eastern Europe and Russia. There are also large Muslim immigrant communities in other parts of the world, such as Western Europe. About 20% of Muslims live in Arab countries, 30% in the Indian subcontinent and 15.6% in Indonesia, the largest Muslim country by population.
The ‘Five Pillars‘ of Islam are the foundation of Muslim life:
- Faith or belief in the Oneness of God and the finality of the prophethood of Muhammad;
- Establishment of the daily prayers;
- Concern for and almsgiving to the needy;
- Self-purification through fasting; and
- The pilgrimage to Makkah for those who are able.
Iman or Faith
“There is none worthy of worship except God and Muhammad is the messenger of God.” This declaration of faith is called the Shahadah, a simple formula that all the faithful pronounce. The significance of this declaration is the belief that the only purpose of life is to serve and obey God, and this is achieved through the teachings and practices of the Last Prophet, Muhammad.
Salah or Prayer
Salah is the name for the obligatory prayers that are performed five times a day, and are a direct link between the worshipper and God. There is no hierarchical authority in Islam and there are no priests. Prayers are led by a learned person who knows the Qur’an and is generally chosen by the congregation.
Prayers are said at dawn, mid-day, late-afternoon, sunset and nightfall, and thus determine the rhythm of the entire day. These five prescribed prayers contain verses from the Qur’an, and are said in Arabic, the language of the Revelation. Personal supplications, however, can be offered in one’s own language and at any time.
Although it is preferable to worship together in a mosque, a Muslim may pray almost anywhere, such as in fields, offices, factories and universities. Oftentimes visitors to the Muslim world are struck by the centrality of prayers in daily life.
Zakah
The financial obligation upon Muslims.
An important principle of Islam is that everything belongs to God, and that wealth is therefore held by human beings in trust. The word zakah means both “purification” and “growth.” Our possessions are purified by setting aside a proportion for those in need and for the society in general. Like the pruning of plants, this cutting back balances and encourages new growth.
Each Muslim calculates his or her own zakah individually. This involves the annual payment of a fortieth of one’s capital, excluding such items as primary residence, car and professional tools.
An individual may also give as much as he or she pleases as sadaqa-h, and does so preferably in secret. Although this word can be translated as “voluntary charity” it has a wider meaning.
Sawm or Fasting
Every year in the month of Ramada-n, all Muslims fast from dawn until sundown–abstaining from food, drink, and sexual relations with their spouses.
Those who are sick, elderly, or on a journey, and women who are menstruating, pregnant or nursing, are permitted to break the fast and make up an equal number of days later in the year if they are healthy and able. Children begin to fast (and to observe prayers) from puberty, although many start earlier.
Although fasting is beneficial to health, it is mainly a method of self-purification and self-restraint. By cutting oneself from worldly comforts, even for a short time, a fasting person focuses on his or her purpose in life by constantly being aware of the presence of God.
Hajj or Pilgrimage
The pilgrimage to Makkah (the hajj) is an obligation only for those who are physically and financially able to do so. Nevertheless, over two million people go to Makkah each year from every corner of the globe providing a unique opportunity for those of different nations to meet one another.
The annual hajj begins in the twelfth month of the Islamic year (which is lunar, not solar, so that hajj and Ramada-n fall sometimes in summer, sometimes in winter). Pilgrims wear special clothes: simple garments that strip away distinctions of class and culture, so that all stand equal before God.
The rites of the hajj, which are of Abrahamic origin, include going around the Ka’bah seven times, and going seven times between the hills of Safa and Marwa as did Hagar (Hajir, Abraham’s wife) during her search for water. The pilgrims later stand together on the wide plains of ‘Arafat (a large expanse of desert outside Makkah) and join in prayer for God’s forgiveness, in what is often thought as a preview of the Day of Judgment.
