The word Islam is derived from the Arabic verb Aslama, which means to accept, surrender or submit. Thus, Islam means acceptance of and submission to God, and believers must demonstrate this by worshiping him, following his commands, and avoiding polytheism. The word is given a number of meanings in the Qur'an. In some verses (ayat), the quality of Islam as an internal conviction is stressed: "Whomsoever God desires to guide, He expands his breast to Islam."[9] Other verses connect islam and din (usually translated as "religion"): "Today, I have perfected your religion (din) for you; I have completed My blessing upon you; I have approved Islam for your religion."[10] Still others describe Islam as an action of returning to God—more than just a verbal affirmation of faith.[11]
