Islam (/ˈɪslɑːm/; Arabic: اَلْإِسْلَامُ‎, romanized: al-’Islām, [ɪsˈlaːm] "submission [to God]") is an Abrahamic monotheistic religion teaching that Muhammad is a messenger of God. It is the world's second-largest religion with 1.9 billion followers or 24.9% of the world's population, known as Muslims. Muslims make up a majority of the population in 47 countries. Islam teaches that God is merciful, all-powerful, and unique, and has guided humanity through prophets, revealed scriptures, and natural signs. The primary scriptures of Islam are the Quran, believed to be the verbatim word of God, as well as the teachings and normative examples (called the sunnah, composed of accounts called hadith) of Muhammad (c. 570 – 632 CE).
