salam

As-salamu alaykum, also written salamun alaykum and typically rendered in English as salam alaykum, is a greeting in Arabic that means 'Peace be upon you'. The word salām has become a religious salutation for Muslims worldwide when greeting each other, though its use as a greeting predates Islam, and is also common among Arabic speakers of other religions, and speakers of languages with Arabic loanwords, such as Indian Christians in the northern Indian subcontinent who speak Hindi-Urdu.
