Hardly. It's paradigmatic Qur'anic sciento-tosh. Ants neither 'speak' (unless you agree that lions or dogs, say, also 'speak') nor 'understand' as both require cognitive abilities, such as conciousness, which they do not have.

Interpreted as science, the Qur'an would be disagreeing with modern science if it suggested ants are capable of formulating complex concepts such as "enter your dwellings, lest Suleiman and his hosts crush you, while they perceive not", as they are not. It is painfully obvious that the verse has nothing whatsoever to do with real-life insect communication and everything to do with being an illustrative anthropomorphic fable, in which context the verse makes perfect sense.

BTW, haven't we done this one before?
