The phrase is Egyptian Arabic for believe me, if I knew I would tell you, transliterated as sadaqny law araf aqolak. No confirmed original recording, performer or release year is documented for this clip, so its history is traced through sharing rather than a known source. It spread as a short voice reaction on messaging apps and meme pages, where the line became shorthand for honestly having no idea. It remains popular because the situation is universal and the wording works without any extra context or explanation needed.
