About Islam

Islam (Arabic: اَلْإِسْلَامُ) is an Arabic word meaning “submission”. Obedience to God is a central theme in the Islamic faith. The monotheistic belief system originated in the 7th century through the teachings of Muhammad (SAW). Muslims believe that Muhammad was the last of all religious prophets (beginning with Abraham) and that the Koran was revealed to him by God.

According to Islamic theology, Islam is the original, complete and universal version of a primordial faith that was revealed many times before through prophets including Adam, Noah, Abraham, Moses, and Jesus.

Today adherents of Islam constitute the world’s second-largest religious group. An estimated 1.8 billion or more than 24% of the world population identify themselves as Muslims. Islam is the official religion in 26 countries in Asia, sub-Saharan Africa, North Africa, and the Middle East.
Islam is growing faster than any other religion worldwide (see: Pew Research Center).

Saudi Arabian Flag inscription, the Shahada
The Arabic script on the Saudi Arabian Flag is the Islamic creed, known as the Shahada; it translates to: “There is no god but God and Muhammad is His messenger.” The Shahada is the first of the five pillars of Islam.
 The two main branches of Islam today, Sunni and Shia
The two primary branches of Islam are Sunni and Shia. The sects split from each other soon after the death of the Prophet Muhammad, over a religiopolitical leadership dispute about the rightful successor to Muhammad.

Sunni

The great majority of the world’s Muslims are Sunnis; its followers make up 87 to 90% of the global Muslim population. Sunnis regard the first four caliphs as legitimate successors of Muhammad. The majority of the Muslims of Indonesia, Pakistan, Bangladesh, Egypt, Jordan, Gaza and the West Bank, and Saudi Arabia are Sunnis. They regard themselves as the traditional (original) followers of the Islamic faith.

Shia

Followers of the Shiite faith reject the first three Sunni caliphs and regard Ali, the fourth caliph, as Mohammed’s first true successor. The majority of Shia Muslims live in Iran, southern Iraq, Lebanon, Bahrain, Azerbaijan, and Yemen. There are large Shia communities in Afghanistan, India, Kuwait, Pakistan, Qatar, Syria, Turkey, Saudi Arabia, and the UAE.

Sufi

Sufism is an Islamic ascetic-mystical tradition, the esoteric dimension of the Islamic faith. Sufism has existed since the early days of Islam and is found in almost all Islamic countries. The devotions of many Sufi orders centre on various forms of the dhikr(ذِكْر), (Dhikr Allah: Remembrance of God). The dedication can be expressed in a ceremony at which music, body movements, and chants induce a state of ecstatic trance in the disciples.

Islamic Core Countries

Islam originated on the Arabian Peninsula in the first quarter of the 7th century. The faith has spread from there all over the world. The traditional heartlands of Islam are listed below.

Islam in the Western World

The European nations shaped by Christianity and the Islamic countries have a shared history of more than thirteen hundred years. Since the 1950s, the immigration of Muslims to Europe has led to the emergence of numerous Muslim minorities in many European countries. Today Muslim communities live throughout Europe. Living together is not always smooth. In recent years, attacks by Islamic terrorists have become more frequent in European countries. But Islamophobic incidents and violent attacks on Muslims have also increased. [7] There is a growing number of European citizens who say that Islam is “fundamentally incompatible” with the culture and values of their country. [8]
