The Arabic word 'Islam' simply means 'submission', and derives from a word meaning 'peace'. In a religious context it means gaining peace through complete submission to the will of God. Muslims believe in One, Unique, Incomparable God; in the Angels created by Him; in the prophets through whom His revelations were brought to mankind; in the Day of Judgment and individual accountability for actions; in God's complete authority over human destiny and in life after death. Muslims believe in a chain of prophets starting with Adam, Noah, Abraham, Ishmael, Isaac, Jacob, Joseph, Job, Moses, Solomon, Jonah, John the Baptist, and Jesus, peace be upon them. They also believe that God's final message to man, a reconfirmation of the eternal message and a summing-up of all that has gone before was revealed to the Prophet Muhammad, peace be upon him, through Angel Gabriel.
