Etymology and meaning

Islam is a verbal noun originating from the triliteral root s-l-m which forms a large class of words mostly relating to concepts of wholeness, safeness and peace. In a religious context it means "voluntary submission to God". Muslim, the word for an adherent of Islam, is the active participle of the same verb of which Islām is the infinitive. Believers demonstrate submission to God by serving God and following his commands, and rejecting polytheism. The word sometimes has distinct connotations in its various occurrences in the Qur'an. In some verses (ayat), there is stress on the quality of Islam as an internal conviction: "Whomsoever God desires to guide, He expands his breast to Islam." Other verses connect islām and dīn (usually translated as "religion"): "Today, I have perfected your religion (dīn) for you; I have completed My blessing upon you; I have approved Islam for your religion." Still others describe Islam as an action of returning to God—more than just a verbal affirmation of faith. Another technical meaning in Islamic thought is as one part of a triad of islam, imān (faith), and ihsān (excellence) where it represents acts of service (`ibādah) and Islamic law (sharia).
