Muslims (Arabic: مسلم, romanized: Muslim) are people who follow or practice Islam, an Abrahamic monotheistic religion. The word "Muslim" derives from Arabic and means "submitter (to God)". Muslims consider the Quran, their holy book, to be the verbatim word of God as revealed to the Islamic prophet and messenger Muhammad. The majority of Muslims also follow the teachings and practices of Muhammad (sunnah) as recorded in traditional accounts (hadith).
