In Arabic, Islam (Arabic: إسلام, lit. 'submission [to God]') is the verbal noun of Form IV originating from the verb سلم (salama), from the triliteral root س-ل-م (S-L-M), which forms a large class of words mostly relating to concepts of submission, safeness, and peace.[39] In a religious context, it refers to the total surrender to the will of God.[40] A Muslim (مُسْلِم), the word for a follower of Islam, is the active participle of the same verb form, and means "submitter (to God)" or "one who surrenders (to God)". In the Hadith of Gabriel, Islam is presented as one part of a triad that also includes imān (faith), and ihsān (excellence).[41][42]

Islam itself was historically called Mohammedanism in the English-speaking world. This term has fallen out of use and is sometimes said to be offensive, as it suggests that a human being, rather than God, is central to Muslims' religion.[
