The will of Allah, to which man must submit, is made known through the sacred scriptures, the Quran (Koran), which Allah revealed to his messenger, Muhammad. In Islam Muhammad is considered the last of series of prophets (including Adam, Noah, Jesus, and others), and his message simultaneously consummates and abrogates the "revelation" attributed to earlier prophets.
