Islam is the religion articulated by the Qur’an, a text considered by its adherents to be the verbatim word of God (Arabic: الله‎, Allāh), and by the Prophet of Islam Muhammad's teachings and normative example (which is called the Sunnah in Arabic, and demonstrated in collections of Hadith). Islam literally means "submission (to God)."[1] Muslim, the word for an adherent of Islam, is the active participle of the same verb of which Islām is the infinitive (see Islam (term)).[2][3]

Muslims believe that God is one and incomparable and that the purpose of life is to worship God.[4] They regard their religion as the completed and universal version of a primordial, monotheistic faith revealed at many times and places before, including, notably, to the prophets Abraham, Moses and Jesus. Islamic tradition holds that previous messages and revelations have been changed and distorted over time.[5] Religious practices include the Five Pillars of Islam, which are five obligatory acts of worship.
