Islam

Islam was founded in 622 CE by Muhammad the Prophet, in Makkah (also spelled Mecca). Though it is the youngest of the world's great religions, Muslims do not view it as a new religion. They belief that it is the same faith taught by the prophets, Abraham, David, Moses and Jesus. The role of Muhammad as the last prophet was to formalize and clarify the faith and purify it by removing ideas which were added in error. The two sacred texts of Islam are the Qur'an, which are the words of Allah 'the One True God' as given to Muhammad, and the Hadith, which is a collection of Muhammad's sayings. The duties of all Muslims are known as the Five Pillars of Islam and are:

1. Recite the shahadah at least once.
2. Perform the salat (prayer) 5 times a day while facing the Kaaba in Makkah.
3. Donate regularly to charity via the zakat, a 2.5% charity tax, and through additional donations to the needy.
4. Fast during the month of Ramadan, the month that Muhammad received the Qur'an from Allah.
5. Make pilgrimage to Makkah at least once in life, if economically and physically possible.

Muslims follow a strict monotheism with one creator who is just, omnipotent and merciful. They also believe in Satan who drives people to sin, and that all unbelievers and sinners will spend eternity in Hell. Muslims who sincerely repent and submit to God will return to a state of sinlessness and go to Paradise after death. Alcohol, drugs, and gambling should be avoided and they reject racism. They respect the earlier prophets, Abraham, Moses, and Jesus, but regard the concept of the divinity of Jesus as blasphemous and do not believe that he was executed on the cross.

Denomination of Islam are the following:

-Sunni Muslims are the largest group in Islam, comprising the vast bulk (80-90%) of the world's 1.5 billion Muslims, hence the title Ahl as-Sunnah wa’l-Jamā‘ah (people of the tradition and union). In Arabic language, as-Sunnahliterally means "tradition" or "path". The Qur'an and the Sunnah (the example of Muhammad's life) as recorded in hadith are the primary foundations of Sunni doctrine. According to Sunni Islam, the "normative" example of Muhammad's life is called the Sunnah (literally "trodden path"). This example is preserved in traditions known as hadith ("reports"), which recount his words, his actions, and his personal characteristics. The classical Muslim jurist ash-Shafi'i (d. 820) emphasized the importance of the Sunnah in Islamic law, and Muslims are encouraged to emulate Muhammad's actions in their daily lives. The Sunnah is seen as crucial to guiding interpretation of the Qur'an. Two major hadith collections are Sahih Bukhari and Sahih Muslim. Sunnis believe that the first four caliphs were the rightful successors to Muhammad; since God did not specify any particular leaders to succeed him, those leaders had to be elected. Sunnis believe that a caliph should be chosen by the whole community.

There are four recognised madh'habs (schools of thought): Hanafi, Maliki, Shafi'i, and Hanbali. All four accept the validity of the others and a Muslim may choose any one that he or she finds agreeable. TheSalafi (also known as Ahl al-Hadith, or Wahhabi by its adversaries) is a ultra-orthodox Islamic movement which takes the first generation of Muslims as exemplary models.

-The Shi'a constitute 10–20% of Islam and are its second-largest branch. They believe in the political and religious leadership of Imams from the progeny of Ali ibn Abi Talib, who Shia's believe was the true successor after Muhammad. They believe that Ali ibn Abi Talib was the first Imam (leader), rejecting the legitimacy of the previous Muslim caliphs. To most Shias, an Imam rules by right of divine appointment and holds "absolute spiritual authority" among Muslims, having final say in matters of doctrine and revelation. Shias regard Ali as the prophet's true successor and believe that a caliph is appointed by divine will. Although the Shi'as share many core practices with the Sunni, the two branches disagree over validity of specific collections of hadith, with Shias preferring hadiths attributed to the Ahl al-Bayt.

Shia Islam has several branches, the largest of which is the Twelvers (iṯnāʿašariyya). Although the Shi'as share many core practices with the Sunni, the two branches disagree over the proper importance and validity of specific collections of hadith. The Twelver Shi'a follow a legal tradition called Ja'fari jurisprudence.^[153] Other smaller groups include the Ismaili and Zaidi, who differ from Twelvers in both their line of successors and theological beliefs. Other smaller branches include the Alawites and Alevi.

-Sufism is a mystical-ascetic approach to Islam that seeks to find divine love and knowledge through direct personal experience of God. By focusing on the more spiritual aspects of religion, Sufis strive to obtain direct experience of God by making use of "intuitive and emotional faculties" that one must be trained to use. Sufism and Islamic law are usually considered to be complementary, although Sufism has been criticized by the Salafi sect for what they see as an unjustified religious innovation. Many Sufi orders, or tariqas, can be classified as either Sunni or Shi'a, but others classify themselves simply as 'Sufi'.

-Minor denominations:

• Ahmadiyya is an Messianic movement founded by Mirza Ghulam Ahmad that began in India in the late 19th century and is practiced by millions of people around the world.
• The Berghouata were a late first millennium Berber sect who followed a syncretic religion inspired by Islam (perhaps influenced by Judaism) with elements of Sunni, Shi'a and Kharijite Islam, mixed with astrological and heathen traditions.
• The Kharijites are a sect that dates back to the early days of Islam. The only surviving branch of the Kharijites is Ibadism. Unlike most Kharijite groups, Ibadism does not regard sinful Muslims as unbelievers. The Imamate is an important topic in Ibadi legal literature, which stipulates that the leader should be chosen solely on the basis of his knowledge and piety, and is to be deposed if he acts unjustly. Most Ibadi Muslims live in Oman, with a number of diasporic communities in Northern Africa.
• The Quranists are Muslims who generally reject the Hadith and/or the Sunnah.
• Yazdânism is seen as a blend of local Kurdish beliefs and Islamic Sufi doctrine introduced to Kurdistan by Sheikh Adi ibn Musafir in the 12th century.
