Outline of Islam

Page Contents

Islam is an Abrahamic monotheistic religion teaching that there is only one God (Allah), and that Muhammad is the messenger of God. It is the world’s second-largest religion with over 1.8 billion followers or 24% of the world’s population, most commonly known as Muslims. Muslims make up a majority of the population in 50 countries. Islam teaches that God is merciful, all-powerful, unique and has guided humankind through prophets, revealed scriptures and natural signs. The primary scriptures of Islam are the Quran, viewed by Muslims as the verbatim word of God, and the teachings and normative example (called the sunnah, composed of accounts called hadith) of Muhammad (c. 570 – 8 June 632 CE).

Muslims believe that Islam is the complete and universal version of a primordial faith that was revealed many times before through prophets including Adam, Abraham, Moses and Jesus. Muslims consider the Quran to be the unaltered and final revelation of God. Like other Abrahamic religions, Islam also teaches a final judgment with the righteous rewarded paradise and unrighteous punished in hell. Religious concepts and practices include the Five Pillars of Islam, which are obligatory acts of worship, and following Islamic law (sharia), which touches on virtually every aspect of life and society, from banking and welfare to women and the environment. The cities of Mecca, Medina and Jerusalem are home to the three holiest sites in Islam.

The following outline is provided as an overview of and topical guide to Islam.

Prophet Muhammad

Muhammad (مُحَمَّد‎) was the founder of Islam. According to Islamic doctrine, he was a prophet, sent to present and confirm the monotheistic teachings preached previously by Adam, Abraham, Moses, Jesus, and other prophets. He is viewed as the final prophet of God in all the main branches of Islam, though some modern denominations diverge from this belief. Muhammad united Arabia into a single Muslim polity, with the Quran as well as his teachings (Hadith) and practices (Sunnah) forming the basis of Islamic religious belief.

Islamic Sacred Texts

The outline of Islamic sacred texts gives readers many informative articles about Islam’s holy books.

The Quran and the Hadith are the two major texts of Islam. These books teach and illustrate Islamic beliefs, values, and practices. They are also important historical documents (especially the Quran), which tell the story of the origins of the Islamic faith.

The Quran is the most sacred text, as it is believed to be the literal word of God (Allah) as revealed to Muhammad. The Hadith is a secondary text that records sayings of Muhammad and his followers. These two texts form the basis for all Islamic theology, practice and Sharia (Islamic law).

Sunnah denotes the practice of Islamic prophet Muhammad  that he taught and practically instituted as a teacher of the sharī‘ah and the best exemplar.

Al-sīra al-Nabawiyya (Prophetic biography) is the traditional Muslim biographies of Muhammad from which, in addition to the Quran and trustable Hadiths, most historical information about his life and the early period of Islam is derived.

Asādʿullāh: Nickname given by Muhammad to describe his kinsman Ali. Asadullah means "Lion of Allah", which is also well known as "IsmāʿīlīLion". Alevism, Bektashism and Sufism consider Ali as the holder of the divine secrets and esoteric meaning of Islam, transmitted to him by Muhammad. "I am the city of knowledge, Ali is its gate." —Muhammad.
