Al-Baqarah 2:78

Waminhum ommiyyoona la yaAAlamoonaalkitaba illa amaniyya wa-in hum illayathunnoon

And among them are unlettered ones who do not know the Scripture except [indulgement in] wishful thinking, but they are only assuming.

And some among them are illiterate who have no knowledge of the Book, but have some fancies and do nothing but conjecture.
