IslamIslam (ˈɪslɑːm; ۘالِإسْلَام, al-ʾIslām ʔɪsˈlæːm, ) is an Abrahamic monotheistic religion centered on the Quran and the teachings of Muhammad. Adherents of Islam, called Muslims, number approximately 2 billion globally and are the world's second-largest religious population after Christians. Muslims believe that Islam is the complete and universal version of a primordial faith that was revealed many times through earlier prophets such as Adam (believed to be the first man), Ibrahim, Moses, and Isa (Jesus), among others.
Prophets and messengers in IslamProphets in Islam (الأنبياء في الإسلام) are individuals in Islam who are believed to spread God's message on Earth and to serve as models of ideal human behaviour. Some prophets are categorized as messengers (rusul, sing. رسول, ), those who transmit divine revelation, most of them through the interaction of an angel. Muslims believe that many prophets existed, including many not mentioned in the Quran. The Quran states: "And for every community there is a messenger." Belief in the Islamic prophets is one of the six articles of the Islamic faith.
QuranismQuranism or Qur'anism (القرآنية) is a movement within Islam. It holds the belief that traditional religious clergy have corrupted religion, and divine law should be derived solely from the Quran. As a result, in matters of faith, jurisprudence, and legislation, Quranists differ from Sunnis, who consider the hadith, scholarly opinions, the opinions of the sahaba, ijma and qiyas, and Islam's legislative authority in matters of law and creed in addition to the Quran.
Twelver Shi'ismTwelver Shīʿism (ٱثْنَا عَشَرِيَّة; DIN), also known as Imāmiyya (إِمَامِيَّة), is the largest branch of Shīʿa Islam, comprising about 85 percent of all Shīʿa Muslims. The term Twelver refers to its adherents' belief in twelve divinely ordained leaders, known as the Twelve Imams, and their belief that the last Imam, Imam al-Mahdi, lives in Occultation and will reappear as the promised Mahdi (المهدي المنتظر). Twelvers believe that the Twelve Imams are the spiritual and political successors to the Islamic prophet Muhammad.
SunnahIn Islam, sunnah, also spelled sunna (سنة), are the traditions and practices of the Islamic prophet Muhammad that constitute a model for Muslims to follow. The sunnah is what all the Muslims of Muhammad's time evidently saw and followed and passed on to the next generations. According to classical Islamic theories, the sunnah are documented by hadith (the verbally transmitted record of the teachings, deeds and sayings, silent permissions or disapprovals of Muhammad), and alongside the Quran (the book of Islam) are the divine revelation (Wahy) delivered through Muhammad that make up the primary sources of Islamic law and belief/theology.
