Question: is it wallah or wallahi?
Answer: Muslims say the scariest things: Wallah and Wallahi. “Wallah” (pronunciation: wah-luh; meaning: I promise by God) is an Arabic expression a person uses to make a promise or express their credibility. ... If you have Somali friends you may have heard a variant of the phrase, “wallahi.” (Pronunciation: wah-law-he).
