(April 2012) (Learn how and when to remove this template message) </Td> </Tr> <P> Wallah (Arabic: وَٱللّٰه ‎, i.e. by God) is an Arabic expression meaning "I swear on Gods name" used to make a promise or express great credibility on an expression typically used as arabic slang . The literal translation is' certainly' or to be certain . It is considered a sin among Muslims to use this phrase and follow it up with a lie . Also, some Muslims argue that this is one of the few valid ways of making a promise, the variant "I promise on myself" or "I promise on my own soul" not being allowed, in contrast to "I promise by the one who holds my soul". i.e. God . An alternative is Wallaahi (وَٱللّٰهِ), "By my God", often contracted by non-Arab populations in Africa to Wallai . Another meaning is "Really?", "Is that so?" (referring to "Do you swear on it?", used in spoken Arabic), "By God!" (this meaning has been adopted by Modern Hebrew slang as well). </P> <P> The Spanish language word for approval' olé' may have been derived from Andalusi Arabic during the Muslim rule of Iberia . </P>
