Tawhid is the Arabic word for the central idea in Islam: God is one and unique. Muslims feel God is unlike any person or thing and has no partners. The Arabic name for God is Allah, a single word used by many Arabic-speaking people.
God sends prophets to guide people. These prophets are human, not divine. They include figures you may know, such as Abraham, Moses, Jesus, and Muhammad. Muslims believe Muhammad is the last prophet. His life and sayings, called the sunnah, are written down in collections called hadith and help explain how to follow Godâs message.
