How accurate are the claims that the song "Tag Tag Tagia" contains offensive meanings and insults against the Prophet Muhammad (peace be upon him) and Lady Aisha (may Allah be pleased with her), and that its origin is Jewish?

We have no knowledge of the true nature of the anthem (Ya Taybah), nor its author, nor its interpretation. It might be a trick from the Jews, or the mentioned interpretation could be an illusion. The matter requires verification and authentication.
