In Arabic, Islam means "submission" and is described as a Din, meaning "way of life" and/or "religion." Etymologically, it is derived from the same root as, for example, Salam meaning "peace" (also a common salutation). A more precise translation of the word Islam would be the serenity that is created by submission. The word Muslim is also related to the word Islam and means "one who surrenders" or "submits" to God.
The religion and philosophy of Islam, is based upon the belief that God (Allah) transmitted knowledge to Muhammad and other prophets (Adam, Abraham, Moses, and Jesus). The followers of Islamic religion, muslims, believe that this revelation to humanity was written down in the Quran, which is the flawless word of God.The theology of the Islamic scriptures informs most aspects of muslim life and culture.
