I studied classical arabic for a short while - it became clear to me that the language very rich, poetic and nuanced, not clinically precise like English - it lends itself to metaphor.
Every language lends itself to metaphor. And since when is English reductively and only 'clinically precise'? There is no language more rich, miscegenated, nuanced and suited to poetry than English. That it can be precise is a function of its capaciousness. Everything you say in this post is predicated on arrant nonsense. In order to make a case for the Quran you just have to say as much ignorant blundering nonsense about other languages, to make classical Arabic appear to have some magical glowing jinn superpowers.
And thats to say nothing about how language becomes rich, poetic, precise, elevated and all other things that language becomes through HOW IT IS USED, by writers, poets, and every day people, not because of any static, inherent, innate qualities. Only the smallest minds think of language in this way.
Sorry if that sounds harsh, but your post stank of more lazy bullshit than I have smelt in some time here.
