The first thing that one should know and clearly understand about Islam is what the word Islam itself means. The religion of Islam is not named after a person, or a place, a tribe, a mountain or a river. Nor is the name just another –ism among the many that exist in the world today. The Arabic word Islam means the submission or surrender of one's will to the only true god worthy of worship, Allah (God in Arabic). A Muslim is the one who submits or surrenders his will to Allah. Hence, it was not a new religion brought by Prophet Muhammad (PBUH) in Arabia in the seventh century, but only the true religion of God re-expressed in its final form.
